Dave Barnes posted this link on Twitter the other night.  It’s some old school Stevie Wonder, recorded live in London, 1974.  The grooves on these tracks are so slamming, although some of the tempos get a little wayward (it turns out the 70’s didn’t have the love affair with a metronome that pop music has now).

Especially noteworthy is the 7-min drum solo in the very first song (which itself exceeds 15 minutes).  The solo ideas meanders here and there, but at one point you can hear the drummer singing along with himself as if his vocal is the centerpiece.

What I’m saying is that it’s cool and you should go listen to it.
