Best known the world over for the group that bears his name, Carlos Santana has been re-inventing and re-shaping the landscape of the known universe's musical culture for close to four decades. A visionary artist with no regards for genre boundaries, Carlos' fluid sound long ago laid claim to the concept of 'world-music' long before the term ever surfaced on pop culture radar. Having evolved and expanded for four decades, the 'Carlos' sound could well be on its way to becoming interplanetary music.
