Which San Francisco funk band released the 1973 album "Tower of Power"?

Which San Francisco funk band released the 1973 album Tower of Power? Tower of Power did. The band released its self-titled third studio album in 1973, cementing its reputation for tightly arranged funk and a distinctive horn section.

Although the group is closely associated with the San Francisco Bay Area, Tower of Power grew from the Oakland music scene. Saxophonist Emilio Castillo and trumpeter Stephen “Doc” Kupka were central to the band’s development, while its horn-driven arrangements helped distinguish it from funk groups built primarily around keyboards, guitar or bass. The album followed Bump City, the 1972 release that brought the band wider attention.

The 1973 album Tower of Power included “So Very Hard to Go,” one of the group’s best-known songs, and showcased its blend of punchy brass, rhythmic precision and soulful vocals. The title can be confusing because it names both the band and an album. Cameo, Mandrill and War were also important funk acts, but none released this particular self-titled 1973 record.
