Brandon Teskey

Brandon Teskey


Brandon Teskey was born and raised in Southern California. By age 5 he was playing with toy guitars and had dreams of becoming a ‘rock star’. After months of endlessly trying to convince his parents to buy him a real guitar, they finally did, and at age 11 Brandon quickly became obsessed, spending hours practicing every day. Brandon was exposed to Blues music shortly thereafter and became consumed with the playing of Eric Clapton, Stevie Ray Vaughan, Buddy Guy, B.B. King, Albert King, Robert Johnson, Albert Collins, and T-Bone Walker, as well as Rock artists like Led Zeppelin, Jimi Hendrix, Pink Floyd, and Eric Johnson. Along with his obsession with guitar playing also came the obsession of song writing and almost as soon as he had picked up the instrument, he began coming up with chord progressions and penning lyrics.

By the time Brandon was 15 years old, he had joined an established blues band with some members forty years his senior and by the time he was 16, he had played the prominent San Juan Capistrano venue The Coach House, where he had seen many of his idols play as a kid. Brandon further developed his playing, becoming intrigued with the technical and harmonic sophistication of players like Scott Henderson, Robben Ford, and Eric Johnson and began studying the works of Jazz musicians like Charlie Parker, Wes Montgomery, Django Reinhardt, and Joe Pass.

Brandon moved to Arizona to attend Arizona State University in the summer of 2003, studying Music and Philosophy. While attending ASU, he met Bruce Jensen where they formed their first Rock band, playing gigs all across the Phoenix valley. Brandon formed and played in multiple bands during his college years and also met his future wife, Cori. Brandon graduated in the Fall of 2008 with a Bachelors of Arts in Philosophy, married his wife Cori, and joined the Army, eventually serving as an infantry captain.

In 2011 Brandon and Bruce formed bluesy hard rock band ‘Corium’. The band released an EP and opened for many national performers across Arizona. In 2011, Brandon began working on his first novel, a historical fiction called, Insurrection; An Epic Novel About the Maccabean Revolt, which was published in 2015, and received notable positive reviews. Brandon released ‘The Chime’, a solo rock instrumental album which combined influences of Rock, Delta Blues, Electronic Rock, and Jazz.

In 2017 Brandon, Bruce, and Chris formed ‘Until the Sun’, which allowed Brandon to return to his Blues-Rock roots and opened up new doors of creativity in his song writing and playing. Brandon lives in Arizona with his wife Cori, and their two children.

Alyssa Swartz

Alyssa Swartz


New section

Alyssa Swartz is an accomplished singer, songwriter, and poet from Joshua Tree, California who began her creative musical journey at an early age. This “Little Mermaid” began singing at the tender age of 6 after seeing the Disney movie of the same name. After perfecting her superstar performances with her hairbrush in front of the mirror, Alyssa began performing at 9 years old in talent shows, musicals, plays and beauty pageants. When she was a teen, local musicians started taking notice of Alyssa’s talents. At the tender age of 16, she quickly found herself partnered up with a rap artist. After seeing her perform several times he asked for an introduction and the two quickly completed an album together titled “Blacksands.” This album was produced by artist Clive Wright from the band Cockrobin who owns a studio in Joshua tree California called Desert Sky Music.

At 17 Alyssa began to refine her natural talent by taking voice lessons. In 2005 Alyssa performed at the i-WARM 50’s in the 70’s & 80’s party bash in Brea California and was featured on the Urban Network as a hot new artist. Her vocal coach encouraged her to sing opera but her heart lead her elsewhere. Success at this level lead Alyssa to compete in the Peoria Idol in 2012, where out of a field of 600, she made it to the finals.

From as far back as she can remember, she had always wanted to be a musical artist and lyricist. Alyssa recounts that when she was little her aunt would pick on her so Alyssa would tell her, “You’re going to regret that when I became famous.” When doing weekend chores and cleaning the house it wouldn’t be unusual to find little notes of encouragement that Alyssa would leave for herself behind picture frames and on mirrors, reminding herself to never give up and always follow her dreams. To this day she has never stopped reaching for those stars.

Some of Alyssa’s claims to fame are performing in Hollywood at a Christmas show for the children of Nat King Cole and Bing Crosby; performing with Vegas musician Father Time; and she acted in a pilot for a television show. More recently she has collaborated with Clive Wright again on several projects with more in the works. Her music has been featured on the radio and she is working on a book of poetry.


Taking influence from artists across the musical spectrum from the Eagles to Celine Dion to Florence and the Machine, she crafted herself into the powerhouse performer that she is today. Hozier, Florence and Don McLean inspire her in her writing.

After being a young single mother for 2 years, fate smiled on Alyssa at 21 when she met her husband Tony on her birthday at a bar. It was as if lightning struck and the two quickly fell in love and married four months later. In 2010 they moved to the Phoenix area from California. Today Alyssa lives in Buckeye with her husband Tony and her two children, Azlynn and Gabe where she writes, sings, and further expresses her artistic talents as a hairstylist. Her artistic talents have not fallen far from the tree and she often partners with her equally talented son. The two can often be found partnering on songs and working on music in their home studio.

Glenn Peacock

Bass Guitar

Glenn’s artistic childhood was guided and inspired by his mother, an artist and musician who had continued a family tradition of introducing music and art early in a developing mind. Early instruments included piano and classical guitar. Electrical bass came into Glenn’s life as a compromise between drums/percussion and an instrument that you could play a minor scale on. Bass was a perfect fit. Glenn became a part of the music scene in Montreal in the mid-seventies which included becoming one of the founding members of Montreal’s “Lyrock” recording and touring to promote a first record and single- “I never want to let you go”. An opportunity to move to the United States presented Glenn with a tough decision which landed him in Spartanburg, South Carolina as a new founding member of Jasmine. A very close relationship with the Marshall Tucker Band through support and executive production from their leadership put the band on the fast track.

Touring and recording and shaping a sound that had deep influence of the US south with a soulful R&B vibe. Glenn also began developing his production abilities working for Sound One Audio and moving in and around the professional audio/audiophile circles. The next stop for Glenn was Scottsdale, Arizona as an invitation by family to come live in Paradise. Paradise Valley that is. Landing in a new place they first thing to do is put a band together. For Glenn, this was a great way to meet people, so he became a founding member of a cover band called AKA which went on to enjoy great success performing in the region to include selling out many Tempe, AZ clubs because of the popularity fueled by performance at many ASU frat parties.

Skill in audio and acoustics found Glenn working with Steve McCarty, a former member of the Steve Miller Band and writer/co-writer of many of the Miller Band’s hits. After building a home studio and a bonding friendship it was inevitable that a band would be formed around the Steve Miller hits and Steve McCarty originals of the day.

As a working professional musician, audio systems and acoustics designer Glenn found himself working with some of the regions larger churches. Becoming a in demand professional in this market has led to working relationships with some of the region’s best performers and singers. In 2022 Glenn joined Until the Sun as a permanent member.
