Jenny Scheinman: Mischief & Mayhem

Protean musician Jenny Scheinman plays all the positions: She's a stellar violinist, a keen improviser, a sharp composer and an appealing singer. This week at the Vanguard she's leading an exceptional group featuring guitarist Nels Cline, bassist Todd Sickafoose and drummer Jim Black in music she whipped up for a previous run here with this band and new tunes besides, no doubt.
