A seven-minute video clip of MEGADETH bassist David Ellefson travelling around central San Jose in Costa Rica earlier today (Thursday, December 1) in search of coffee and postcards can be seen below.MEGADETH is scheduled to perform tonight at Estadio Rosabal Cordero in Heredia, Costa Rica with support from CHILDREN OF BODOM. MEGADETH's new album, "TH1RT3EN", sold 42,000 copies in the United States in its first week of release to land at position No. 11 on The Billboard 200 chart. The band's previous CD, 2009's "Endgame", opened with 45,000 units to debut at No. 9. This was slightly less than the 54,000 first-week tally registered by 2007's "United Abominations", which entered the chart at No. 8. 2004's "The System Has Failed" premiered with 46,000 copies (No. 18) while 2001's "The World Needs A Hero" moved 61,000 units in its first week (No. 16). "TH1RT3EN" was recorded at MEGADETH mainman Dave Mustaine's Vic's Garage studio in San Marcos, California with producer Johnny K (full name: John Karkazis), who has previously worked with DISTURBED, SEVENDUST, MACHINE HEAD and STAIND, among others. The artwork was once again created by artist John Lorenzi, who worked on the last two MEGADETH studio albums, 2007's "United Abominations" and 2009's "Endgame", as well as the band's 2007 box set, "Warchest". "TH1RT3EN" marks the recorded return of bassist David Ellefson who was part of the band's classic lineup from 1983 to 2002. In a move that delighted the band's legion of diehards, Ellefson returned to performing live with MEGADETH in early 2010 and has remained a fixture on the stage ever since. This is the first time Ellefson has played on a MEGADETH record since 2002's "Rude Awakening".
