He's hosted WXPN's Star's End for 26 years. Played ambient music live for 20 years. Has been booking like-minded synth heads for his Gathering concerts for 14 years. Maybe it's time you did something for Chuck Van Zyl. Start by paying into his and guitarist Art Cohen's improvisational space-duo The Ministry of Inside Things. One, because MoIT, in its decade-plus existence, hasn't played out too much. Two, because MoIT's dense, high whines and low room-rumbling—a bubbly, dublike mix of Tangerine Dream, Klaus Schulze and King Tubby—must be experienced live to be felt. (That said, they've got a brand new live CD, Contact Point, that offers ready, raw contradiction in vividly pulsing tunes like "Fortescue.") Lastly, because this show benefits The Corporation for Innovative Music and Arts of Pennsylvania. That's fine. But do it for Chuck.
