MEGADETH are back at work on their fourteenth studio album, with producer Johnny K (aka John Karkazis).

Frontman Dave Mustaine tweets: "Johnny made it in. Record 14 is officially underway. Clips to upload tomorrow. Thrashin' time!"

Megadeth's new album is expected in early 2013, via a label to be announced. The band recently parted ways with Roadrunner Records. A message (released on December 10th) from Mustaine states: "Today marks the end of an era with Roadrunner. Hopefully we can finish strong with a Grammy."

Nominations for the 55th annual Grammy Awards were announced on December 5th by The Recording Academy and reflected an eclectic mix of the best and brightest in music over the past year, as determined by the voting members of The Academy. For the fifth year, nominations for the annual Grammy Awards were announced on primetime television as part of "The Grammy Nominations Concert Live! — Countdown To Music's Biggest Night", a one-hour CBS entertainment special broadcast live for the first time ever at Bridgestone Arena in Nashville, Tennessee. The 55th annual Grammy Awards will be held on "Grammy Sunday," Sunday, February 10, 2013, (8:00-11:30 p.m., live ET/delayed PT) at Staples Center in Los Angeles.

"The Grammy Awards process once again has produced a diverse and impressive list of nominations across multiple genres," said Neil Portnow, President/CEO of The Recording Academy. "This year's nominees truly represent an exceptional and vibrant creative community that exemplifies some of the highest levels of artistry and excellence in their respective fields. Combined with the fifth year of our primetime nominations special, we're off to an exciting start on the road to Music's Biggest Night, the 55th annual Grammy Awards, on February 10."
