Erika Wennerstrom has visited our studio before with her Americana-rock band Heartless Bastards. This year, the singer and guitarist took a break from that band to release her debut solo album, "Sweet Unknown." Inspired by a trip to the Amazon rainforest, the record features a more psychedelic sound for Wennerstrom, whose robust vocals are always a riveting aspect of her music. Wennerstrom returned to the CPR Performance Studio last month before a show at Denver's Globe Hall. She played four songs and spoke with Alisha Sweeney about how taking a break from Heartless Bastards helped her songwriting, writing the album on a camping trip in West Texas and how she connects with people through music.
