I don't know much about Fernando's Kitchen, but I do know that I saw them busking on the London Underground on a Friday night on the way home and they were pretty good, with a crowd gathering to listen and miss a train or two. When busking I heard them with two artists, one guitar and one percussion but the album has what sounds like a clarinet and a bass player to boot. Their site can be seen here: http://fernandoskitchen.co.uk/
