Walfredo previously worked with Carlos Santana, Gloria Estefan, Ricky Martin, Sergio Mendes, Sinverguenza, and Steve Winwood among others.

In January 2009, Drew Hester joined Chicago as a temporary replacement for Tris Imboden who was undergoing medical treatment at the time. After Tris returned to active duty, Drew remained part of the touring band as an auxiliary percussionist.

The band issued the following statement regarding Drew's departure:

"Drew Hester notified Chicago that due to his primary passion of playing drums, he would leave the touring band to pursue this passion. Chicago has hired Walfredo Reyes on percussion, who will blow your mind, being a perfect fit for the touring band. In a short amount of time, he already fits the Chicago ensemble like a glove."
