I'm not familiar with the Berklee controversy. But the venue only holds 100 people, and he did 2 shows. I went to the second show and it was nearly full, for whatever that's worth.
I don't remember what my first box set was, but my first Mosaic was the Larry Young box. Also, my box collecting has been exclusively CDs.
I don't necessarily listen to boxes often, but I find that I've been buying them more often lately. Especially boxes with lots of extra and/or live tracks and videos that have previously been unreleased. Sometimes the Alt versions are more interesting than the commercially released ones - especially with rock music.
