Members of the Holy Rolling Empire have known one another since grade school and came together as a band in 2005. The group released its first album, "Gigantus," in 2009.

Fans of Holy Rolling Empire won't want to miss the chance to see the psychedelic-pop quintet Friday night.

The band headlines a benefit show for a proposed low-power FM community radio station that hopes to begin broadcasting from downtown in January. It will be the band's last Tucson show in "a very long time," said lead singer Orin Shochat.

"It will be a special show for me," said Shochat, who is moving to Los Angeles within the next couple of weeks to work in television soundwork. With his move, he said, the band will turn its focus more on California.

California's gain is Tucson's loss. Holy Rolling Empire has been a constant presence in the Tucson music scene since the band began in 2005. The group's members have known one another since grade school and throughout high school at Canyon del Oro.

Holy Rolling Empire signed to Tucson-based Burning House Records, which released the group's debut album "Gigantus" in 2009. The Star's Kevin Smith called the album "a truly great collection of bouncy, poppy, psych-rockers that add up to one of the most cohesive local releases in a while. There's a consistent alternate-universe feeling and colorful sound running throughout."

The band followed up in June 2010 with a seven-track EP, "Noise Will Be Noise," and played showcases at South By Southwest that year, earning a reputation outside of its hometown.

The band is now working on a demo that showcases the band's maturity in style and content.

"You can definitely tell it's Holy Rolling Empire," said Shochat, 28. But the band has had more time to focus on writing, producing music that is "almost more simplistic ... We're not writing weird parts just to be weird," he said.

Holy Rolling Empire heads a lineup that includes Blind Divine, led by Sacred Machine museum and curiosity show co-owners Paula Valencia and Daniel Martin Diaz; and the self-taught rock trio The Wolfgang, which is playing its first show together since it played Plush last September.

Proceeds from Friday's show at La Cocina downtown would buy equipment needed for the station, being spearheaded by Jason LeValley.

LeValley is hoping to get the necessary permits and funding to launch the station as early as January.

The community station would headquartered at Access Tucson downtown, and could broadcast live music performances simultaneously on TV and radio, LeValley said. The station would have a range of eight to 10 miles, LeValley said.

Like KXCI, Tucson's other community radio station, this one would broadcast a combination of music and talk.

But unlike KXCI, whose music tends to be more adult contemporary and mellow, LeValley's station would emphasize harder-edge, possibly rock-oriented music with plenty of local bands in the mix.

"This station won't be afraid to play metal or punk," LeValley said.
