Colfax Speed Queen has been a can't-miss live act in Colorado's music scene for several years. The Denver garage rock band's concerts involve crowd-surfing and mosh pits while the band delivers high-energy guitar and organ riffs. Colfax Speed Queen last November released its sophomore album "Talk To Your Doctor." We recently welcomed the band back into the CPR Performance Studio for the first time since 2013. The band members played a few songs from the new album and spoke with Alisha Sweeney about channeling their live energy in the studio, making a split single with fellow Denver band The Ned Garthe Explosion and some recent tour memories in Kansas City.

Singer and guitarist Kyle Emerson may be familiar to fans of Colorado's music scene as a member of the psych-rock band Plum. That group relocated to Los Angeles last year but Emerson is back in Denver to release music under his own name. His debut EP "Worth It" is out next week and he celebrates with a release show May 11 at Hi-Dive. Emerson and his band stopped by the CPR Performance Studio to play four songs from the new EP. He also spoke with Jeremy Petersen about assembling a new band for his solo work, recording live to tape and how his solo work differs from the music of Plum.

The story of Bison Bone begins in Oklahoma, where singer and guitarist Courtney Whitehead launched his music career playing at barnyard parties. Eventually Whitehead made his way to Denver, where he recruited singer Brianna Straut after watching her perform a Gillian Welch song at 3 Kings Tavern. Bison Bone recently released its debut album, "History Of Falling." The country-rock band stopped in for a studio session just before its release. The quintet performed four songs from the album and spoke with Jeremy Petersen about the band's origin, recording the album mostly live and the influence of artists like Woody Guthrie and JJ Cale.

Flobots recently returned to the CPR Performance Studio to preview some new music from their forthcoming album "NOENEMIES." The Denver hip-hop band explores the power of protest music on the new record. It features call-and-response choruses written to empower protesters and performed by members of the Denver community. The band performed three songs in the studio, backed by Denver gospel group Spirit Of Grace. The members also spoke with Alisha Sweeney about recruiting people to sing on the album, their upcoming live shows in Colorado and the themes behind songs like "Sleeping Giant."
