By the time we get to Woodstock, we may be drowning in 40th anniversary retrospectives and reissues. Of course, that doesn’t mean that some of them aren’t worthwhile.

The product avalanche picks up momentum Tuesday, as Sony Legacy unleashes “The Woodstock Experience” — a 10-CD boxed set that focuses on the performances of Santana, Janis Joplin, Sly and the Family Stone, Johnny Winter and Jefferson Airplane and includes 25 previously unreleased tracks and six posters.
Rhino has already rolled-out remastered versions of “Music From the Original Soundtrack and More: Woodstock” and “Woodstock Two” to coincide with the re-release of the “Woodstock” documentary on Warner Home Video.
But the big prize will come from Rhino Aug. 18 with “Woodstock — 40 Years On: Back to Yasgur’s Farm.” The six-CD boxed set will sequence the 77 songs in the order they were played at the festival, including 38 previously unreleased tracks, as well as a few firsts — the entire set list of the festival in the liner notes and Max Yasgur’s entire address to the crowd — as well as stage announcements and, fittingly, the sound of rain.
