Noah Gundersen released his third album, “White Noise,” last September. It marks a shift in the Seattle singer-songwriter’s folk music. Gundersen brings in a backing band on several songs to give the record a fuller, uplifting rock sound — though he includes some plaintive piano ballads as well. Gundersen visited the CPR Performance Studio accompanied by his sister Abby on violin. He played stripped-down versions of two songs from “White Noise” along with a new B-side. He also spoke with Jeremy Petersen about the decision to retool his sound, reconnecting with his siblings by playing music together and learning to embrace his early musical output.

Merrill Garbus sings about racism, white privilege and climate change on the experimental duo’s fourth album.

The Hollow formed in 2013 and released its self-titled debut EP two years later. Since then, the Denver rock band has been fairly quiet while retooling its sound and lineup by recruiting former Epilogues drummer Jason Hoke. The quartet is back this year with the guitar-heavy EP “Contact,” recorded in Evergreen, Colo. The Hollow made its debut in the CPR Performance Studio earlier this month. The band members played four songs and spoke with Alisha Sweeney about the new lineup’s first year together, using drones to film the music video for “Sleep Talkin'” and how writing their music is therapeutic.

Grayson County Burn Ban features members of Denver rock bands Bud Bronson & The Good Timers, The Kinky Fingers and Ned Garthe Explosion. The quintet dubs its blend of rock and Americana “campfire country,” which features pedal steel guitar along with typical rock ‘n’ roll instruments. Last week the band released its debut album, “Better Neighbor.” Grayson County Burn Ban stopped into the CPR Performance Studio to play four songs. The members also spoke with Bruce Mitchell about the band’s origin, why they love country music and their involvement with Denver nonprofit Youth On Record.

Since playing a session in our studio last year, iZCALLi wrote and recorded its fourth album. The Denver rock band released “IV” last week with a show at the Bluebird Theater. The self-produced record finds the band expanding from a trio to a quintet and continuing to blend English and Spanish lyrics with Latin and psychedelic music. iZCALLi played three songs from the new album in the CPR Performance Studio. The band members also spoke with Alisha Sweeney about expanding its sound with strings and horns, integrating Latin rock into Denver’s music scene and their experience as U.S. immigrants over the past year.

Rubedo last joined us in the CPR Performance Studio shortly after the release of its album “Love Is The Answer” in 2013. Since then the members of the Denver trio stayed busy playing in bands like Wheelchair Sports Camp and Kyle’s Xmas Supergroup. Rubedo returned last month with “Vaca,” a new album that pays tribute to their late producer Ikey Owens. Rubedo played three songs from “Vaca” in our studio. The band members also spoke with Alisha Sweeney about Owens’ influence on their music, opening a pop-up shop in downtown Denver for the “Vaca” release and working with graffiti artist Mike Giant for the album cover.
