Drummer Frank Rosaly and trumpeter Jaimie Branch have played some extended Monday-night engagements at Pilsen’s Skylark this past year, and starting tonight they’re hosting a bona fide series there, with different acts each week. The Ratchet Series kicks off with a quartet featuring guitarist Matt Schneider, phenomenal saxophonist Tim Haldeman, bassist Anton Hatwich, and drummer Dylan Ryan (Herculaneum, Bronze). The music starts at 10 PM and there’s no cover–though of course the musicians won’t turn up their noses at donations. This past summer, when I caught a Skylark gig by Princess, Princess, Rosaly’s trio with Branch, the group had to compete with the yammering of diners and drinkers–with any luck the bar and the music will evolve a compromise.
