Walfredo Reyes Jr. (born Walfredo de los Reyes Palau IV; December 18, 1955) is a Cuban American musician who is an expert in drum set and auxiliary percussion, and a music educator and clinician. He has performed with many jazz, Latin, World music, World fusion, Afro-Cuban, and rock bands as a touring, session recording, and full-time player/performer. Reyes is known for his fusion of many of the world's percussion techniques, including the ability to play a drum set with his hands in addition to the traditional use of drumsticks; it was said that he can "sound like a drummer and a percussionist at the same time". He was a member of Santana and joined Chicago as the percussionist from 2012 to 2018, at which point he took over the drum seat. He also performed in the band of former Nazareth guitarist Manny Charlton. Reyes is the title character of the Phish song "Walfredo".
