That was my initial motivation for getting this disc - but Ben's playing is very interesting, and the tune he wrote is nice, and the way he connects to the tunes written by the other players on the date. Ben with Thad Jones and Zawinul ....
The three tracks missing are alternates, one with Thad, the other two are quartets - has anyone here heard them on the Milestone twofer? If they are without reverb, it would mean that was added afterwards. But I hesitate to buy a used copy of that double LP, since I already have the other date - the Bill Harris Fantasy LP with Ben.
I can remember a mention of the reverb when the album was reviewed in Down Beat at the time of its original issue. Can't find the review online.
