Woodstock soundtrack, not just an album but a piece of history

Woodstock: Music from the Original Soundtrack and More is a live album of selected performances from the 1969 Woodstock counterculture festival.
The triple soundtrack album Woodstock was originally released by Atlantic's Cotillion on May 11, 1970.
It topped the Billboard Charts for four weeks and sold two million copies.
These LPs don’t show the historical sequence of the festival, the selected tracks have been re-ordered (and edited) for a sense of flow.
This has been the subject of much debate, but we have to say that this album works better as a document than as an album.
Most of the tracks selected have some form of stage announcement, conversation by the musicians, etc., lengthening the tracks to an extent.
That give people a sense of the experience, that is more important than the audio quality, for which we have to mentioned the veteran producer Eddie Kramer, the sound engineer during the three-day event.
