Eva Cassidy 'Live at Blues Alley' Proof positive She could sing any song, any genre, better than almost anyone.
Emmy Lou Harris 'Spyboy' Maybe the best album she ever made.
Jewel 'Have A little Faith In Me' from the 'Phenomenon' soundtrack. She morphs into Janis Joplin halfway through the song as her band channels 'Big Brother & the Holding Company. Amazing. Totally worth finding.
