Roger Humphries began playing professionally at the age of fourteen. He led his own group at Carnegie Music Hall when just sixteen. "I've had a love for music as long as I can remember." He was encouraged by his older brothers Lawrence Jr. and Norman who were musicians at that time. Additionally, Roger's son Roger Jr. and Norman's son Gregory have followed in their footsteps as professional drummers.
After playing with various groups around the country, ace drummer Roger Humphries decided to organize his own group in 1972 which he calls RH Factor and in 1996 he assembled Roger Humphries' Big Band. Roger gives special thanks to Dr. Harry Clark, principal of The Pittsburgh High School for the Creative and Performing Arts (CAPA) who has allowed him to have such a beautiful experience teaching the kids at the school, and also to Dr. Nathan Davis who gave him an opportunity to teach and shares lives with students at the University of Pittsburgh. Roger has influenced the careers of a number of his students and musicians also through participation in a number of clinics such as the Slippery Rock University Summer Jazz workshop, Mellon Jazz Masters Class and Concerts, and the teaching goes on especially on the stage.
