Tower of Power: What is Hip—Live at Iowa State UniversityTower of Power has been issuing albums and touring the world since the early 1970s when their album Bump City lit the fuse to a string of classic hit releases, including “What Is Hip?,” “Back to Oakland,” “Urban Renewal,” “In the Slot,” “Ain't Nothin’ Stoppin’ Us Now,” and “Live and in Living Color.” This 1987 live concert at Iowa State University highlights the music that has had the band in demand as backup artists to Elton John, Santana, Bonnie Raitt, Huey Lewis, Little Feat, David Sanborn, Michelle Shocked, Paula Abdul, Aaron Neville, Aerosmith, Michael Bolton, Billy Preston, Public Image Ltd (PiL), Rod Stewart, and Toto. Tower of Power's horn-driven sound is not to be missed.
