Jed,
I agree. The Cowboy Junkies' Trinity Sessions is one of the great albums. It seems like everything recorded at the Church of the Holy Trinity in Toronto turns out to be fantastic (Sheryl Crow recorded an amazing show there, tracks of which turn up on special editions of her albums occasionally.). The combo of Margo's sweet voice, and Trinity's amazing acoustics is pretty special. I would say that the CJ's rendition of "Sweet Jane" may eventually become THE definitive version of the song, as opposed to the Velvet Underground's original take on it. Margo makes my list of all-time favorite female pop vocalists (see below).
1. Karen Carpenter
2. Harriet Wheeler from The Sundays (Please God let them release another album!)
3. Margo Timmins from Cowboy Junkies
4. Hope Sandoval from Mazzy Star
5. Beth Orton
