Carlos Santana is one of the great musicans of the current era. This album includes many guest artists and yet the constant through all the tracks is Carlos's playing. I love the first three Santana albums, but have not purchased anything since this album (apart from one disappointment). Carlos started playing the blues and this is evident in his music. This sound of this album is classic and is complemented by so many other good musicians. A bonus is 'The Calling' highlighting Eric Clapton. There is hardly a dud track.
