In September 2015, Perry and Subatomic Sound System launched a 40th anniversary tour for Perry's 1976 album "Super Ape". The tour began as part of Dub Champions Festival and continued over the next two years with more than 50 dates in North America and some isolated dates in Europe. Nearly every show was sold out on the 2015 and 2016 tours. It culminated with the release of the "Super Ape Returns to Conquer" album in September 2017 which debuted at number 2 on iTunes US reggae chart behind Bob Marley's remastered "Legend" album, and on number 3 on the "Billboard" reggae chart. Larry McDonald performed as part of the band and on the recorded album. A Kickstarter campaign was organized in 2015 by Emch of Subatomic Sound System to raise funds to build a custom 15-foot-tall gorilla similar to the one on the original album cover art. The Kickstarter campaign reached its goal and the gorilla appeared on stage during 2015 and 2016 tour dates.
