Composers Lisa Schonberg and Allan Wilson lead the confounding percussive ensemble Secret Drum Band. The aptly named collective’s intricately arranged work is full of mysterious, disorienting sounds that range from familiar to alien. Blown-out tribal beats converge with industrial aesthetics against a backdrop of ambient soundscapes. Complex environmental issues and naturalistic concepts propel these sonic explorations, such as the plight of protected species and humanity’s impact on specific ecosystems. In short, the group’s hypnotic music will have you both tapping your feet and scratching your head. Catch Secret Drum Band on Tuesday, April 10, at the Higher Ground Showcase Lounge in South Burlington. Mirah headlines.
