Darren Garvey spent the last two years as the percussionist for Colorado folk group Elephant Revival. That band recently went on hiatus, but Garvey is staying busy with his solo singer-songwriter music. Next month the multi-instrumentalist will release his latest album, "Heart Attack Sleeves," and he performs June 29 at the Walnut Room with Tough Old Bird and Perry West. Garvey stopped into the CPR Performance Studio to play some of his own material on guitar and piano. He also spoke with Alisha Sweeney about producing his own records, his goal to share a new song online every week in 2018 and why Elephant Revival is taking a break.
