nmperign + Peter Evans and Sam Pluta

Snugs, a series of avant-jazz solo performances at 61 Local, celebrates its first anniversary with a striking double bill, featuring two tight-knit improv duos: nmperign (9:30pm)—the exacting, hyperminimal pairing of trumpeter Greg Kelley and saxoponist Bhob Rainey—and the electroacoustic team of trumpeter Peter Evans and laptopper Sam Pluta (8pm).
