I've heard almost all of it also, and missed out on buying this CD when it was affordable. I agree on the front line, have always considered the brothers functional, but not front line. The singer/pianist got a lot of airplay in his brother's band around that time - "Expansions" was my theme song for one of my college radio shows ("Leaving This Planet" was my theme song for my other one - remember, it was the early 70's). Of the 56 original Strata-East releases, I've heard 51 in full, owned 46 of them at one time or another (I was able to come by them easily in Philly in the 70's), and currently own 25 of them on CD. Biggest MIA's for me that are on CD are the Cecil McBee and the Weldon Irvine (neither of which are really great albums, but they're good), and the one we are talking about here. Biggest MIA's because they've not ever made it to CD are the Mtume (personnel and era/feel make it essential, though it is underrehearsed and sloppy), the Shirley Scott (best album she ever did), the Harold Vick (ditto) and the awesome Jazz Contemporaries "Reasons in Tonality". Would also be nice to have the Cosmic Twins, the other Jazz Contemporaries, the Charles Davis, and the Brass Company on CD. The ones I've never heard in full are The Descendants of Mike and Phoebe (one of many Bill Lee projects on the label), the other John Gordon, the Muriel Winston, the Bruce Johnston/Rodney Jones, and the Billy C. I've heard parts of some of them.
