Black Sabbath -- Get ready to crank up the "War Pigs," buddy! Because the full catalog from the original Black Sabbath lineup is finally available digitally in the U.S. Ozzy Osbourne, the group's legendary lead vocalist, properly sums up this historic occasion: "It's about (expletive) time the first eight Black Sabbath albums were made available on iTunes in the U.S." Guitarist Tony Iommi adds, "Great news, been a long time trying to explain to fans why the music wasn't available." The albums are available exclusively at iTunes (www.iTunes.com/BlackSabbath). Also, see a great slideshow of Black Sabbath in concert here.

Dire Strait is kind of, not really, getting back to together. OK, Mark Knopfler isn't involved, so nobody is really going to care all that much about this partial reunion. Still, there might be two or three folks out there who are marginally interested in learning that Dire Straits' Alan Clark and Chris White and some other musicians are touring as "The Straits." Shockingly, the tour is set to play mostly smaller venues. Listen to what Dire Straits is supposed to sound like by clicking on the accompanying playlist.
