I know what you mean. I played once with my drum teacher's classic rock band. He built them up so much, "this is probaly the best musicians you'll ever play with." (umm yeah right) After about 100 blues progressions, I got up there, and my friend, much older, a drum teacher, not mine was like, this kid wants to play some jazz! The bassist, (electric) looked over at the keyboardist, and said "you ever hear Milestones?" He said, "No," so he just did a fast progression, that swung. That bass player couldn't keep a steady bass line for his life. Well it got to my solo, and I 'blew the house down.' But the music sucked.
