Previously, many thought that the Mamat Khalid-helmed "Rock" franchise would end with "Rock Bro! Kembali Ke Pangkal Jalan". However, the well-known director has now surprised everyone with the new "Rock 4: Rockers Never Dai". Mamat said that aside from him missing the rock scene, the movie is also made in hopes of introducing the rock era to today's youth, who's not as exposed to the music genre that was popular in the 1980s to the 1990s. "Rock 4" is the continuation of "Rock Bro!", where Dio who went into a coma following an accident with Rimba Bara, is now back and realises that today's music has changed a lot. Determined to continue the legacy of rock, he forms Rimba Bara Dua along with Rayyan, Omar, Seri and Acap.
