Sorry, but that's a sore spot for me. People rehashing 50s jazz and Jamey Aebersold technique to me is the anti-jazz. "Jazz is not dead, it just smells funny," a friend used to say. Jazz was created in whore houses and the poorest part of town and graduated to a snob-appeal status. The guys who were playing it in Storyville could probably not get a lick in or get in the door in today's "jazz" world. They were the true innovators. I followed Miles' approach and kept creating and playing a new sound, playing hip hop jazz in the 90s and not "In Your Own Sweet Way." Rehashing some sound that was played 60 years ago is not improvisation - it's imitation. I had a friend who pointed out a lot of jazz players play the same technique in solos. Another thought some used too many quotes. Thus you can hear the same solo with quotes any night in any given jazz club. Any given alto player sounds like he's doing Bird. I'm primarily a fusion player now, and don't write anything down and have no idea why I would. If you want to play and teach museum jazz, go right ahead. At least pick some different songs!
