The addition of The Bad Plus to our blogroll got a positive review. Here they are, recorded by some guy in the back of the room with a hand-held camera, playing Nirvana's "Smells Like Teen Spirit." (Here is the original, and here is Paul Anka.) Usually I like my jazz a little less adulterated -- and the Bad Plus have stirred up considerable controversy by mixing in frequent pop covers along with their straight-ahead tunes. But these guys are playful, intelligent, and infectious, as well as accomplished musicians. The blog is worth reading, too -- here's a thoughtful commentary on Barack Obama and discrimination in jazz. Besides, it's named "Do the Math"!
