Kawashima was accepted into the BMI Lehman Engel Musical Theater Workshop, making him the youngest person to join the group until Robert Lopez (who later won a Tony Award for writing Avenue Q) took that honor.
In the dance world, he has collaborated as composer and sound designer on several new works with Bessie-Award-winning and Tony nominated choreographer David Neumann including Pearl River and the Central Park SummerStage concert performance featuring beat-poet John Giorno.
Commissioned for the Celebrate Brooklyn Festival, Deep Six extended the collaboration to include veteran New York musicians Gary Seligson on drums and Dave Philips on bass.
As a musician, Kawashima has been a producer and an arranger for major label and independent artists including American Idol's Nikki McKibbin, and several other projects for multi-platinum mixer Andy Zulla.
He currently resides in Pleasanton, California as a Designer at Apple, with his wife, Lisa Walter, and their three daughters, Adrienne, Cameron and Deirdre.
