I've been meaning to take a closer look at Eva Cassidy's "Nightbird" collection of Blues Alley recordings ever since I heard of it a while ago. What makes this collection interesting is a number of unreleased live tracks for this unknown-Washington D.C.-performer, which Apple classifies as "Pop." (That's ironic, since Eva Cassidy once answered Blue Note A&R flacks so: "I Don't Do Pop Crap!")
