Producer/songwriter/arranger/keyboardist Randy Muller was the leader of '70s disco/funk/pop band Brass Construction, whose "Movin'," which was produced by Jeff Lane, became a number one R&B single in 1976. Muller also produced hits on Salsoul Records acts Skyy and Cameron. He arranged B.T. Express' million-selling 1975 number one R&B/number four pop hit "Express" and Shirley Caesar's gospel classic "No Charge." Though they are most known for the driving "Movin'," the band could get melodic and mellow (ex. "The Message (Inspiration)"). Brass Construction, Earth, Wind & Fire, and other '70s-era funk/soul/pop bands were the inspiration for the acid jazz genre of the '90s.
