My current music crush
I have slowly fallen in love with the site "The Ultimate Bootleg Experience" (aka T.U.B.E.).
They offer (illegal, I'm sure) complete downloads of bootlegs of concerts and concert video.
At times I have been really impressed by the quality of the sound. They usually spell out if it's from a soundboard connection, broadcast over FM or if it's a crowd recording (which usually sound the worse, but can have a certain charm - in the middle of the third song on the 2009 Steely Dan show, you hear some woman announce in a nasal voice, "These are our seats." which really puts you in the live moment).
What finally put me over the top was a posting of a late 70s Steely Dan show with the original lineup. I had always wondered what they sounded like. Answer: good.
Btw, they have many more artists than Steely Dan.
Enough babble, go check it out.
