Boston, as we have been howling for the past few weeks, is a jazz desert. Art Hodes is undoubtedly good, but Lawrence remains inaccessible except for the hardiest hikers and most jazz-starved enthusiasts. And the commendable plans of a group of Lowell House Freshmen to import bands for series of Saturday afternoon jam sessions are destined to be stillborn unless an angel appears suddenly.

The only good news to appear in the past few weeks is good enough to make up for everything else. Commodore Music Shop has finally brought out its new, enlarged, corrected, up-to-date edition of Delannay's "IIot Discography." The binding still cracks disconcertingly, the arrangement is still awkward, the lists of personnel are still incomplete in a few places, the index is still inaccurate (v. Louis Armstrong), and no-doubt, the experts will find a few still uncorrected mistakes. But if you're at all interested in collecting hot you can't afford to be without "Hot Discography."
