MEGADETH mainman Dave Mustaine has posted the following messages on his "verified" Twitter account:March 4: "Celebrating being married to my best friend of 20 years and 1 day. At a famous resort near our beautiful city; we snuck away from it all!" March 6: "We had a great anniversary. Time to finish preparing for the tour. Going to church today to pray for my fans and the tour to all be blessed." MEGADETH and SLAYER will team up for the "European Carnage Tour 2011" in March/April. Mustaine revealed during an online chat in November with members of the band's official fan club, Cyber Army (formerly MegaFanClub), that MEGADETH had "five songs almost finished" for its next studio album. Mustaine was also scheduled to go over the new material at the band's Vic's Garage studio in San Marcos, California with engineer Ken Eisennagel, who previously worked with MEGADETH during the pre-production phase for 2009's "Endgame" and 2007's "United Abominations" CDs. Mustaine said in a recent interview that MEGADETH's new album is shaping up to be "more like 'Endgame', maybe sticking in that vein and going a little forward toward what I like." Speaking to Australia's FasterLouder, Mustaine said he preferred "Endgame"'s more aggressive moments. "We were forced, in a way, to have to do certain things and it's really easy for me to blame somebody, but at the end of the day it was my fault, I could have said no, but I didn't," he said. "I was nervous that we were going to end up getting kicked off the label. I figured I would rather go underground and play what I like, and not sell as many records, but still be able to look myself in the face in the morning."
