third album for the band. It featured soul singer Lenny Williams on lead vocals and Lenny Pickett on lead tenor saxophone. Bruce Conte replaced guitarist Willie Fulton and keyboardist Chester D.Thompson also joined the band during the recording of the album. The album spawned their most-successful single "So Very Hard to Go". Although the single peaked at #17 on the Billboard Hot 100, it landed in the Top 10 on the surveys of many West Coast Top 40 radio stations, hitting #1 on many of them. The album also charted two other singles on the Billboard Hot 100, "This Time It's Real" and "What Is Hip?" 1974's Back to Oakland spawned another hit, "Don't Change Horses (in the Middle of a Stream)", that reached #26 on the Billboard Hot 100, and "Time Will Tell", which charted at #69. The funk-jazz classic instrumental "Squib Cakes" also came from this album. On Urban Renewal (1974), the band moved more toward funk than soul; however, they continued recording ballads as well. Williams left the band in late 1974, and was replaced as vocalist by Hubert Tubbs. Though the band remained popular, their days of chart radio airplay declined. During the late 1970s they briefly tried recording disco-sounding material. On January 12, 2017, long-time drummer David Garibaldi and bassist Marc Van Wageningen were hit by a train as they walked across tracks before a performance in Oakland. They both survived the accident. According to their manager, Jeremy Westby, they were both “responsive and being treated at a local hospital”. They fully recovered and returned to the active lineup later that year.
