Glenn Kotche and So – Percussion’s new collaborative Drumkit Quartets has the opposite of a clever name, though the album doesn’t suffer for it. And while hearing Wilco’s legendary avant-drummer compose music for four drum kits would probably be quite compelling, it’s also wise to remember that Kotche’s sprawling set-up in Wilco is one of the few in the modern rock biz to rival elder skinbashers like the Grateful Dead’s Mickey Hart or Rush’s Neil Peart. Instead, Drumkit Quartets comes tapping in warm electronic-treated tones (“Drumkit Quartet #3, Mt 2”), kit-to-crickets disintegrations that never lose their rhythmic cool (“Drumkit Quartet #6”) and the occasional bell cascade (“Drumkit Quartet #3, Mt. 3”). Traditionally kinetic showoff moves get buried amid experiments including, most intriguingly, percussion parts rendered as tapped-out laptop typing, laughter, silence and other noises (or absence thereof) on “Drumkit Quartet #50.” The album reaches its apex with the closing “Drumkit Quartet #51 (Chicago Realization),” where a lush hum makes a bed as marimbas clatter atop one another like a steady, pleasant, tuned rain on the roof. Other electronic ghosts arrive and depart, but the marimbas are insistent. Sometimes, percussion is all you need.
