The majority of the tracks are performed entirely by Henry and his drum machine, he often collaborates with Dan Taylor (Chunkstyle) playing bass guitar, and he has collaborated once with GOAT on The Tunnel from Metroid II, and with Daniel Brown (Kareshi) in the Downed Frigate from Metroid Prime. Henry's brother Adam also provided drum parts for the Super Metroid ending. The logo features Samus Aran's sprite from Metroid, holding a guitar. This may be a reference to the special unlockable ending in Tetris where she is seen playing a bass along with other Nintendo characters.
