Mosaic Records was mentioned in another post recently. I thought maybe they deserve a more prominent plug, for the benefit of those who might not know of the outfit already. Check 'em out at mosaicrecords.com. They have a terrific catalogue, the items I've bought from them are all first rate. Their box sets are exceptionally good, with rare material, good sound quality, and the accompanying books are well written and contain great photos. Get on their mailing list. Their catalogues are printed on glossy stock and always contain an interesting history lesson.
