Composer and violinist Jenny Scheinman has a new band called Mischief and Mayhem. Perhaps the mischief part comes where hazy, dreamy grooves from the Heartland meet the experimental jazz quirks of Brooklyn. Certainly, it’s a band capable of raucous and rocking mayhem, thanks in part to the presence of Nels Cline, the man Wilco hired to perform its guitar freakouts. Whatever the etymology, Scheinman and the band are soon to embark on another week at the hallowed jazz hall known as the Village Vanguard. WBGO and NPR Music will be there for a live radio broadcast and live video webcast on Wednesday, Aug. 17 at 9 p.m. ET. Check this page for a link to the video and live chat.
