Caravanserai is the fourth studio album by Santana released in October 1972. It marked a major turning point in Carlos Santana's career as it was a sharp departure from his critically acclaimed first three albums. Original bassist David Brown left the group in 1971 and was replaced by Doug Rauch and Tom Rutley, while original percussionist Michael Carabello left and was replaced by Armando Peraza. Keyboardist/vocalist Gregg Rolie, who was having a falling-out with Santana, was replaced by Tom Coster on a few songs. Caravanserai reached the top 10 of the Billboard 200 chart in 1972.
