I’ll Tell You What! marks the first time RP Boo has released an album of contemporary material shortly after creating it. The title, a favorite maxim of his, welcomes listeners to sit down and let him narrate in the unforgettable abstract fashion that he is known for. He explores familiar motifs, such as the cosmos, movement, and opposition, using densely interwoven vocals, unpredictable percussion, and evil humming bass as his tools of choice.
