I just picked up this cd. My experience is mainly based in R&B/Funk & Jazz and I'm not too familiar with Mike Porcaro's work. Was he really that good a bassist? Also, I heard a couple of cuts with some slap bass. Was that Mike? Most of what I've heard about him did not include slap bass. If that is him, he's a pretty decent slapper. By the way, the cd is killin'!! Thoughts?!
