Thanks for pointing that out, John. I've been an avid listener of B-Tribe since about the mid-nineties. Mind you, I've only just discovered that B-Tribe is really a German studio musician called Claus Zundel! You learn something new every day. I haven't heard all of Santana IV yet. In fact, I've only got as far as Fillmore East up to now, but I love that spacy Doors seventies feeling that piece conjures up. I'm looking forward to hearing the rest.
