Caveat pro emptor!
(Buyer beware)
This upcoming release is put together by 'Classic Rock Legends' and let's just say their track record is absolutely brutal!
Their
modus operandi is
usually to get their hands on/purchase a rare piece of short video from
a band's history/discography, create a 2-hour documentary on it and
then market it into an "ultimate" review of said band with 'previously,
unreleased and very rare footage' (read as: grainy, and poor bootleg
video).
They have done this with many a band: Genesis, Floyd, Yes, etc etc.
Their productions are not condoned/sponsored by the bands in question, and the resultant quality is thus quite poor.
Don't say I didn't warn you!
