In its continuing mission to promote the Bakersfield country legacy of Buck Owens and the Buckaroos featuring Don Rich, Omnivore Recordings will issue two collections that spotlight the town’s most storied musicians: Don Rich’s That Fiddlin’ Man from 1971, and the all-instrumental The Buckaroos Play Buck and Merle, which marries the 1965 LP The Buck Owens Songbook and 1971’s The Songs of Merle Haggard.
