Sly & Robbie.

If you dont know, these guys have done session/production work for Bob Dylan, Rolling Stones, Grace Jones, Joe Cocker, Carlos Santana, James Brown and many more.
It was an awesome lecture.
Even better live jam session in the studios.
EVEN BETTER concert in the Barri Gotic Square.

One of the best concerts ive seen...sound was incredible. Run tings rude bwoy.
