Ex-pat Milwaukee musician turned record producer Cheryl Pawelski is a good ol' rock and roll aesthete. Sure, she's got a house full of CDs out in L.A., but like the rest of us record geeks, she appreciates the power of the object. That's why she and her fellow Omnivore Recordings co-owners create things like the four 10"s released for Record Store Day this past holiday season. The discs spotlight classic country artists Buck Owens, Merle Haggard, Wanda Jackson and George Jones.
