Just over eight years after their last full-length collaboration, Starlito and Don Trip are back at it again with the release of Step Brothers 4 Life, out now via the rapper's respective labels Grind Hard and MRVL Recording.

Step Brothers 4 Life boasts 16 songs that feature the Tennessee rappers' signature rhymes filled with double entendres and plenty of references to pop culture.

The introspective duo released a lyric video for "Madden Curse" and an official video for "Royal Rumble", with the latter song featuring samples of popular wrestling themes and legendary wrestling commentator Jim Ross.

Check out "Royal Rumble" below:

Lito and Trip also dropped a 44-minute documentary going behind the scenes of making the fourth installment, where the rappers answer questions from an iPad and talk about each track on the album.
