Montevallo native Garrett Crosby produces music under the name Holly Waxwing. The currently Birmingham-based electronic artist creates playful menageries of sound from disparate places and samples everything from top 40 and Mariah Carey to Episcopalian psychedelic folk. His EP Peach Winks was released earlier this year. WBHM’s Em Wiginton spoke to him about how he creates his music. Holly Waxwing performs this Saturday at the Desert Island Supply Co. in Birmingham.
