Surprise! While we were focusing on the biggest of box sets over at The Second Disc, Atlantic quietly released a disc of unreleased vintage material from Southern rockers Black Oak Arkansas.

One of the top touring acts of the early 1970s, Black Oak Arkansas - with its triple-guitar lineup and idiosyncratic vocal style of Jim "Dandy" Mangrum - earned a great deal of acclaim in studio and on the road. Earlier this year, Mangrum reunited with original members Rickie Lee "Risky" Reynolds (rhythm guitar), Jimmy Henderson (guitar) and Pat "Dirty" Daugherty (bass) and returning latter-day members Johnnie Bolin (drums since 1985), George Hughen (bass since 1985) and guitarists Hal McCormack (since 2003) and Buddy Church (since 1989) to record five new tracks for Atlantic (their first major label home), including lead single "Plugged In and Wired" and a cover of Bob Dylan's "I Shall Be Released."

But Back Thar N' Over Yonder is only a third new; the remaining tracks are drawn from three years of sessions with legendary producer Tom Dowd at the famed Criteria Studios in Miami - all never before released. It's a new chance to discover the oft-underrated power of Black Oak Arkansas - who, in frontman Mangrum, many have seen a prime influence for some of the biggest frontmen in rock in the '80s, including David Lee Roth and Axl Rose.

In addition to Back Thar N' Over Yonder, Atlantic has also digitally released The Complete Raunch N' Roll Live, a 2007 title from Rhino Handmade that expanded the original 1973 live album Raunch N' Roll to two discs featuring two shows from 1972. Taken together, there's a lot of boogie rock to get you going, even a month after its release.

Check out the specs for both and place your orders after the jump!
