Maiden Voyage is special to me since I acquired it very early in my collecting, and it didn't register with me at first. I bought it hoping it was like Headhunters, and when it didn't have that same electric funk vibe I was disappointed. I shelved it, returned to it later on after my ears grew some, and loved it.
Inventions & Dimensions is outstanding. "Mimosa" is a favorite.
I was reading this thread the other night and was shocked to see I don't yet have Takin' Off, something I intend to rectify ASAP.
