Credited to Rauch, Rolie and Santana, this splendiferous guitar instrumental which runs to 3 minutes 54 seconds segues from the opening track of the Caravanserai
album. According to Simon Leng in Soul Sacrifice: The Santana Story
, this "is where the emotional action cuts in, with a simple two-chord concept, startling time signature shifts and intense percussion. Most noticeable was the sound and performance of Santana's guitar which hits the listener with a more refined brand of passion, a clear advance in technical control and a less blues-based, more horn-like tone."
"Waves Within" segues into "Look Up (To See What's Coming Down)."
