SF Bay Area stalwart improvisor David Leikam has had his band zBug going for quite a few years now. On a recent Sunday, Disaster Amnesiac was happy to catch their set at Temescal Arts Center in Oakland, at which time David graciously gave me a copy of Splitting Glass/Twilight Sunrise. What one gets on this CD is basically two versions of each of these titles: one full version and one that is edited. Smart move, really. Radio stations would probably be more inclined to jam the latter, while fans of improvised music would likely dig on the former just as much. And there is a whole lot of sound to dig. David gets really wild sounds out of his Moog and electric bass. He builds these huge walls of sound that are "based on architecture". The percussive vim of Sheila Bosco pushes the music forward with great energy, and guitarist Fred Malouf gets all manner of texture from his axe. Splitting Glass/Twilight Sunrise is a heavy blast of what Disaster Amnesiac keeps thinking of as Industrial Jazz as I've listened. Surely this term has been used before, but it definitely describes the sound of zBug. They're a band that packs a real whallop live, and David has bookings for 2020 set up. Get on out and support them!
