If you've listened to a horn section on a 1970s record and thought, damn, that's a good arrangement, there's a decent chance Randy Brecker had something to do with it. He came up in Philadelphia, went through Indiana University's jazz program, and landed in New York right as the line between jazz and rock was getting interesting to blur. He played with Blood, Sweat & Tears early on, did a stint with Horace Silver, and co-founded the band Dreams with drummer Billy Cobham — all before he and his brother Michael put together the group that would define his career.
