Recorded by Bob Brookmeyer with the Ed Partyka Jazz Orchestra (Madly Loving You – Challenge Records), this piece was written as a birthday gift for Bob Brookmeyer. Bob was my mentor, teacher and friend for many years. Writing for him was daunting, but to this day, I marvel at his playing on this piece. I do not own rights to the recording, but surely you can find it. "Anthem" obviously features valve trombone which makes it limiting to most groups. It also requires five reeds, 3 french horns, 4 trumpets, 3 trombones, bass trombone, tuba, bass and drums. This instrumentation is obviously a limiting factor for most groups, but it creates wonderful colors – a whole new palette.
In the case that you don't have a wonderful soloist on valve trombone (it's pretty tough to find), I've include a solo part for guitar, which I think could be a nice option, but I will admit, I've not had the chance to try it myself.
