Revelations (Santana song)

"Revelations" is an instrumental song by Carlos Santana that was originally released on the album Festival. The song starts with solo piano, then more instruments are added, such as electric guitar, strings, and different types of drums. As the song progresses, the tempo and volume increase, and more guitars are layered upon each other. At the end, Santana uses his Wah pedal, one of the few effects he is known to use throughout his career. The song was written by Santana and keyboardist Tom Coster.
