On August 17, 2006, Soulfly played the 10th Annual D-Low Memorial show with several guest artists including Dave Ellefson and Roy Mayorga, the latter of whom who currently plays with Stone Sour. Most notably, Max was reunited onstage for the first time in 10 years with his brother Igor Cavalera. Max and Igor formed Sepultura together in the early 1980s, but had not played together since Max's departure in 1997. Igor joined the band midway through the set for a jam on the drums and stayed onstage to play the Sepultura classics "Roots Bloody Roots" and "Attitude" on Joe Nunez's drum kit.
