If you've ever purchased any bootlegs or pirated copies of official music releases, were they clear, professional sounding products?

This survey was inspired by my recent acquisition of a triple-CD bootleg of a 2002 New Hampshire concert by Ratdog, one of Bob Weir's bands after the dissolution of The Grateful Dead, for about $1 at a Goodwill store. The Dead, their associated bands and many other jam bands that have followed in their wake have allowed their concertgoers to record their shows and trade those recordings among themselves, if not necessarily sell them for profit. Have you ever bootlegged a concert you attended, with or without the permission of the act whose performance you recorded? (the Ratdog concert linked with this question took place four days before the show on the CD set I bought)

Not all bootleg records come from concert recordings, Others come from stealthily (illegally?) obtained studio recordings or sessions recorded for non-commercial use. For instance, around the time The Beatles' label issued a 2-CD set of the band's work for a BBC Radio show prior to their US breakthrough, a fellow writer for a magaznie I was contributing to at the time purchased a 10-CD bootleg of the entire run of that show (linked with this question is a selection of excerpts from that show which didn't make the official release). What's your experience with purchasing studio bootleg material?

My only two conscious purchases of pirated material were 1)a cheaply-produced cassette copy of rapper LL Cool J's third album, Walking With A Panther, bought at a black festival the summer it was released (regretted that!), and 2) getting a CD of the only real album by The Justified Ancients of Mu Mu (The JAMs), a British duo who would later become The KLF (The Kopyright Liberation Front) and score a couple of US pop hits; the second album was banned from sale and all remaining LP copies-one of which I already bought-destroyed after the members of ABBA threatened legal action for the act's generous, unauthorized sampling of "Dancing Queen" (the track that prompted the threat of litigation is linked with this question). What experience have you had with pirated music?

I've given you much to read (and hear!), but one last question: since the muscians who make music that is bootlegged and pirated don't make any money from their work sold in those forms, do you feel bad for having deprived income from performers whose work you enjoy if you've bought their bootlegged or pirated music?
