Award-winning Producer/Rapper Lil Jon has asked John and Zack to come build him a tiny recording studio right in his backyard! He's looking for something completely functional he can record his next big hit in, but his wife Nicole is hoping this tiny... (more) house can replicate the style of their big house and also serve as a guest space for their family and friends. John and Zack will have to figure out how to balance the mix in the space without scratching the record.
