"Official" bootlegs

[Kane Knight]

What's out there for "Official" Bootlegs? That is, Bootlegs released officially by bands?

Examples:

Aerosmith--Live Bootleg
Morphine--Bootleg Detroit (One of the hottest sounding Bootls I've ever heard)
Velvet Underground--Final V.U. (AKA Final View), plus a couple others that I can't think of...
I know there's a ton of Greatful Dead Official Boots, but I've never listened to them or owned them...

Pearl Jam releases about 3 or 4 bootlegs every year. They don't sell them online anymore though. :(

[The Destroyer]

3 or 4? I think they released a few more than that...

Neurosis have started issuing them, but I've not bothered to check them out. Meant to be good though.

Actual bootlegs, or are they like the live albums they've been releasing, which are official and professionally recorded?

Morphine's Bootleg Detroit was a boot that was recorded on low-fi by someone in the crowd. When a couple members heard it, they decided to digitally master it and release it as a live album. Same sorta deal with Aerosmith's "Live Bootleg." Is it that kinda deal, or just a live recording?
