We're told the jukebox was invented in 1890, but it certainly came of age in Depression-era America, and it not only ‘downloaded’ individual singles but eventually encouraged over-the-counter sales too. Logically then, the programming of the current release follows the order in which the singles appeared, rather than the strict order of recording, so there's a greater variety of instrumentation than we're accustomed to track-to-track, with different sessions providing each other's A and B sides. (Did you know that ‘Round Midnight’ was first backed with ‘Well You Needn't’, two future standards for the price of one?) Of course, the reissue then cheats by augmenting those 29 singles tracks with the 14 extra takes and three whole new tunes that surfaced in the LP era, so this is as complete as any previous reissue. Oddly, I can see no credits for remastering and, apart from a higher volume level, this sounds the same as earlier Rudy Van Gelder remasters – i.e. very good. You ask about the music? As well as the original versions of classic tunes, we have Monk at his most intense and concentrated so, if you don't have the material, you need to now.
