(Associated Press) – A founding member of the Isley Brothers who helped perform such raw rhythm and blues classics as “Shout” and “Twist and Shout” and the funky hits “That Lady” and “It’s Your Thing,” Rudolph Isley has died at 84.

A Cincinnati native, Rudolph Isley began singing in church with brothers Ronald and O’Kelly and was still in his teens when they broke through in the late 1950s with “Shout,” a secularized gospel rave that was later immortalized during the toga party scene in “Animal House.”

Rudolph Isley left the group in 1989 and became a Christian minister.
