Because, despite what that last option is, we all KNOW, deep down, that Thick is not only the best Tull epic ever, but the best Tull album/song, best prog album/song, best album/song ever, period, bar none, etc. Forever. BBF...best, uh, boring fingering. For a flute. Best bombastic flute. Yeah.
Anyhoo, these are specifically the really, really long Tull songs. So, no "My God" through "Black Sunday" here, just good ole fashioned "If it's not a full record, it hardly deserves to be here" type stuff.
And, were it not for a purchase on my part but recently, I would have had to have said "Baker Street;" not because it's super-fantastic (entertaining yes, but superfantastic? No), just because I like it more than Passion. But now, oh, now, how I've heard the VERY Thick worthy Chateau D'isaster tapes. Have you? No? You really should have. It's what Passion Play would have sounded like if Tull had played it. In other words...well, superfantastic.
