Pulled this one out last night, and frankly, I don't understand the vehement reaction against Def & Kweli. They sound all right to me. Far worse a breach of taste is The Roots bluster on Caravan, which seems like so much name/cultural connection dropping w/little interest in doing anything at all related to the original song (something that I definitely can't say about the Black Star lyrics, which seem organic - no pun intended - to the song). Oh well, different strokes and all that....
The real killer on the disc for me, and one that I had completely forgotten about, is the version of Star Crossed Lovers by Propellerheads w/Martha Wainwright. My god what a fresh sounding cut that is. The use of the melody is incorporated in a thoroughly ingenious manner, as a background figure to the vocal hook. It works, and it works well. The lyrics are gentle yet firm, and the whole thing grooves like a mofo.
Don't really know Propellerheads (informed comments welcome), but if this cut is representative of their overall output, I've been missing out.
