Earlier tonight (Thursday, March 28), Dave Mustaine ran into country legend Willie Nelson at a restaurant in Austin, Texas, where the MEGADETH mainman has been "house hunting." Mustaine tweeted: "Willie Nelson is in the restaurant I am eating at. I just met him! How cool is this???" A short time later, Mustaine took to Twitter again to post a photo of him talking to Willie about a possible guest appearance on the song "The Blackest Crow", which will be featured on MEGADETH's new album, "Super Collider".In a recent interview with the "Shockwaves"/"HardRadio" podcast, Mustaine stated about "The Blackest Crow": "The slide guitar is something that I played a long time ago when I was in PANIC and I never got a chance to use it in METALLICA, 'cause we just weren't doing that, but I did have Southern influences, and that's 100 percent apparent when you look at what I wrote with [the METALLICA demo song] 'Mechanix', and then when we changed that and it became 'The Four Horsemen', the part that I showed James [Hetfield] and Lars [Ulrich] was 'Sweet Home Alabama'. 'Cause I was a [LYNYRD] SKYNYRD fan. I mean, I wasn't a dyed-in-the-wool, bell-bottom-wearing Southern guy, but I liked their music and I really dug the brawniness of their music. So, yeah, I do like Southern rock. One of my favorite guitar players, when he first came out, was when Zakk Wylde first came on the scene. I thought he was just like the perfect, all-around rock guitar player — the way his image was, the way he dressed, the way he played, the way he looked, the way he acted. And I guess we all kind of change and grow up and grow old and grow apart and grow tired, or this or that, and there's always gonna be a new young gunslinger on the scene that's gonna come in and that's gonna make you forget your heroes. But that's one of the things I liked about Zakk and he made such a great impression on me when he came on the scene. There's not a lot of guitar players like him." "Super Collider" is scheduled for a June 4 release via Mustaine's new label, Tradecraft, which is distributed by Universal Music Enterprises(UMe). Mustaine sang the very last note on the album on March 13 at his Vic's Garage studio in San Marcos, California. Horn player Bob Findley — who previously appeared on the track "Silent Scorn" from MEGADETH's 2001 CD, "The World Needs A Hero" — is a featured guest on the song "A House Divided" on the new album. Other tracks set to appear on the effort include "Super Collider", "Forget To Remember", "Dance In The Rain", "Burn" and "King Maker". "Super Collider" is MEGADETH's first release since its recent split with Roadrunner Records. With the recent acquisition of EMI, UMe now brings together MEGADETH's classic, 14-year, seven-album Capitol catalog, which includes one multi-platinum release ('92's "Countdown To Extinction"), four platinum records ('86's "Peace Sells... But Who's Buying?" ; '88's "So Far, So Good... So What?"; '90's "Rust in Peace"; '94's "Youthanasia"), and one gold ('97's "Cryptic Writings"). In all, the band has scored five U.S. Top 10 albums (including 2007's "United Abominations" and 2009's "Endgame") and two Top 5 releases, with 2011's "TH1RT3EN" debuting at No. 1 on the Billboard Hard Rock Albums chart.
