(Serena) Utah Miller is a Baltimore-based singer-songwriter and composer. Miller first showed an interest in music at age three, when they began humming the scores of movies they'd just seen. At age five, they taught themself how to play drums when their grandfather gave them an old kit for their birthday. At ten, they were eager to learn guitar, so their father gave them lessons until they were ready to begin playing with others and enrolled in the program at Baltimore School of Rock. For more than six years, they performed dozens of shows, singing and playing every instrument: lead and rhythm guitar, bass, keys, drums, and saxophone. They also performed with SoR's Show Team, the small performance troupe of the best students in the program.

In middle school, Utah played saxophone in band, and their abilities landed them a spot at the elite Baltimore School for the Arts, from which they graduated. They were accepted into both Berklee School of Music and Peabody Institute. Through a program with Johns Hopkins and the City of Baltimore, they earned a (mostly) full scholarship at Peabody, which was the deciding factor. They graduated from Peabody in 2020 with two Bachelor's of Music degrees in Composition and Computer Music, with a minor in Saxophone. 

Utah played in their first band with their grade-school classmates at age 11. The Oxi-Morons played dozens of gigs, mostly at local block parties and festivals. By their teen years, Utah was performing with their cousin, bassist Gray vonBriesen, keyboardist Mack Watson, and SoR drummer Jakob Coburn, as Legends of Et cetera. Utah, then 15, was the lead vocalist, guitarist, and songwriter for the band.

Legends released their first album, Coyote, when Utah was 17, and they became the youngest band to ever perform at WTMD, winning a coveted Live Lunch spot at their annual Baltimore Band Block Party. They also played two in-studio concerts, An Evening With Legends of Et cetera, the second after the release of their second full-length album, Cardboard City. Legends remained on WTMD's playlist for several years.

While the band took a break to attend college in different states, Utah began their solo project, San Junipero, releasing an album during the height of the pandemic. San Junipero's new EP, Cherry Pit, was released in January of 2026. 

Transgressive Records recording artist Julien Chang invited Utah and Gray to be his backup band, which took them across the Eastern U.S. and to the U.K. to play the Pitchfork Music Festival in 2022.

In 2025, Legends of Et cetera, now LOETC, began performing live again as a trio, sans keys.
