It seemed an odd combination: minimalist master Philip Glass jamming with auteurs of overabundance Bang On A Can All-Stars. And, at times, it was – two of Glass’s groundbreaking works from the ’60s, "Music in Similar Motion" and "Music in Fifths," sounded even more disjointed than the usual music being banged.

Glass aficionados were disappointed that the composer was a mere "special guest" and only performed for a third of the show. The last time Glass was in concert at Royce Hall was for the multi-night retrospective called "Philip On Film" where the composer played for two hours straight each evening, satiating even the most hardcore fans. This time around, however, the composer almost appeared lazy in his dearth of onstage time.

Glass and Bang On A Can All-Stars redeemed themselves, however, when they concerted on the melancholic "Closing," from Glass’s seminal Glassworks. Here, the combined strengths of the two melodic masters – Glass is at his best with melancholy Bang On A Can when they tap on the can – amalgamated into, non-coincidentally, the perfect closing.
