The amazon.com reviewer hits it right on the nose regarding this set. Stravinsky was not a conductor at the start of his career, but began to conduct his own works in public in the 1920s when he was in his mid-forties, doubtless in part because he needed the income. Some of his earliest recordings are not entirely successful (at least in my opinion), but by the time he made the ones in this set in the early 1950s, he was truly expert in getting his players to produce what he had in mind, as much as any composer/conductor I can think of. Sometimes his recordings feature studio or pickup groups that are not quite on par with the top orchestras, but they often are, and his performances are always well worth hearing.
Amazon's reviewer mentions the splendid Histoire and Octet. Stravinsky did stereo versions in 1961, though the stereo Histoire features Los Angeles musicians, including violinist Israel Baker, rather than the New York-based musicians in this 1954 version, which includes violinist Alexander Schneider. All of these are excellent, but the Histoire and Octet here, in excellent mono sound, get my vote as more dramatic and exciting overall.
The original LP of the Histoire and Octet is a rare collector's item (the excellent notes to this set, by Tim Page, actually mention this), and the CD sound is superior to that of the original LPs, so it's great to see this set at a low price again. Grab it quickly before only the expensive ones are left.
