WOW! this afternoon I played a song (a Night in Tunesia/The Melody still Lingers On)with 7 bass players and a drummer from my conservatory. My bass teacher wrote the arangement , and it was absolutley awesome! The song was divided in 7 layers, I played the Syntesizer and bass part, 2 guys played the solos, somebody else played the vocal melody etc. I don't know if anyone else ever played with a group of bass players, but with the right arrangement it can be really really cool !
