“O.C. Smith began as a jazz vocalist and later moved into country and R&B,” reports AllMusic. After singing in Count Basie‘s band in the early ’60s, Smith then moved into into a unique soul/country mix, scoring a hit with “Son of Hickory Holler’s Tramp.”
Smith then went deeper into the soul genre. “Little Green Apples,” released in 1968, went to #2 on both the pop and R&B charts. Later in life, he became a pastor of a Los Angeles church while also continuing to perform and record until his passing in 2001.
