"Stravinsky Ballets box set, Dorati, Speakers Corner Mercury reissues", as Rushton mentioned. Its a good thing Speakers Corner picked up the licenses for these. Petrouchka and the Rite of Spring are sonically very good, and Firebird is one of those 'pinnacle of the vinyl medium' offerings. SC has done a wonderful job with the slipcase, booklet, and covers.
Its taken me a while to realize what everyone else probably knows: Stravinsky was a genius - a rhythmic devil who stretched and broke the bounds of his musical context in fantastical ways. Pricey, yes, but you may not want to let these lapse.
