When nature calls, you gotta go. Now, men can create screaming licks in an unusual way with Billboard Brasil’s “Guitar Pee,” an electric guitar/urinal hybrid which is currently touring Sao Paulo drinking establishments. After a few beverages, men take a trip to the bathroom to find the music making machine. Aim for the string “triggers” and create your own rocking solo. When their performance is complete, users can visit guitarpee.com on a mobile device or computer and listen to their MPEE3.
