Four music-biz vets formed Omnivore Recordings in 2010, and since then they’ve released a steady stream of interesting-looking reissues. It took me a while to take note, though last year I reviewed an Alex Chilton collection on the imprint called Free Again: The “1970” Sessions. That anthology brings together tracks the pop genius cut as his first band, the Box Tops, was disintegrating, capturing a raw pop glow that presaged the emergence of Big Star. Still, it wasn’t until last fall, when the label announced a slew of vintage country reissues, that I started paying close attention.

Of late, they’ve released Heartbreak, a 1982 album by the great English folk guitarist Bert Jansch cut in Los Angeles, and on February 5 comes Sunshine Boy, a two-CD collection of demos and unreleased studio material from Townes Van Zandt. But what really caught my eye was a couple of titles with music culled from the vaults of Bakersfield country icon Buck Owens.
