Arnie has worked with U2 since 1988 and in 2005 he won the coveted Grammy Award for his work on  “How To Dismantle The Atomic Bomb”. Arnie originally joined The Mastering Lab in 1968 and together with Doug Sax etched the sound that made independent mastering the only way to go. His mastering skills honed to a fine point from his years at The Lab and elsewhere have put him in high demand at both Warner Bros and A&M studios. Arnie’s return to The Mastering Lab in 2007 is truly a reunion of old friends, many lifelong clients of The Mastering Lab are cheered by his return.
