Fan-filmed video footage of their appearance can be seen below.DOWN's latest EP, "Down IV Part I - The Purple EP", was released on purple vinyl on February 26. "Down IV Part I" sold 12,000 copies in the United States in its first week of release to debut at position No. 35 on The Billboard 200 chart. "Down IV Part I - The Purple EP", DOWN's first in a series of four EPs to be released over the next few years (with a year between EPs), each touching on a different aspect of the band's sound, came out on September 18, 2012. "Down IV Part I - The Purple EP" heralds the sound of DOWN going back to its roots, with influences from BLACK SABBATH, SAINT VITUS and WITCHFINDER GENERAL. SEPULTURA will reunite with producer Ross Robinson (KORN, LIMP BIZKIT, SLIPKNOT) to record their next album, tentatively due before the end of the year via Nuclear Blast Records. The CD will be tracked in June at Robinson's studio in Venice, California and will be co-produced by Steve Evetts, who previously worked with SEPULTURA on the "Nation" (2001), "Revolusongs" (2002) and "Roorback" (2003) albums, in addition to having collaborated with Ross on a number of other projects in the past.
