A quiet jazz album. Not much Miles trumpet on side one, but a reasonable amount on the superior title track. All the musicians are now legendary and well-known. Not actually ambient as many critics claim, but just laid back and very loosely funky, albeit repetitive. I know it well, so have difficulty listening to it with fresh ears and can't say if it is actually boring because recognition makes it pleasant. Certainly an easier listen than Bitches Brew and perhaps the opposite in terms of noise and jazz rock to my personal favourite A Tribute To Jack Johnson. Still a good and importantly progressive electric Miles Davis jazz record.
