Singles, the latest collection of tracks from Teef, echoes another era, with beats centered on a combination of keys and patterned, percussive grooves. It’s that relaxed, sitting back in the pocket, before flowing free with a smooth air that locks things down. However, that chill state can quickly ramp up, switching the musical plot into suspenseful drama. Teef will be laying it down at Connie’s Ric Rac on Thursday, March 30, as part of the Biz Mighty Variety Show.
