THE WEEKLY INTERVIEW: GUSTER DRUMMER BRIAN ROSENWORCEL
Guster began in the mid-’90s as a folk-leaning trio fond of busking in Harvard Square. In the years since, the band has moved on to more traditional concert venues, and augmented its plaintive acoustic guitar-and-bongo songs with instrumental color. New LP Evermotion adds shimmering keyboards, blocky synths, twinkling percussion and psychedelic-pop flourishes to the palette.
