here's a snippet of a very soft glock solo, commissioned by Justin Greene (reading through above)

Commissioned by Justin Greene, atoms is for solo glockenspiel. The exclusive use of ping pong balls as mallets/sound generators explores a decidedly different side of the typically (very) loud instrument. atoms culminates in some particularly gnarly two-in-one-hand ping pong ball action. Approximately 7.5 minutes in duration. Score available here.
