In 1989, he left the band after the completion of the Louder Than Love recording sessions. A theoretically predicted alternative arrangement for porphyrin rings relies on 16p anti-aromatic bonds, where interaction among double bonds creates an unstable network. Unlike most surf music, which tends to feature either the guitar or the drums, Stereo Donkey emphasizes all three instruments- with Yamamoto's bass providing a fresh, melodic sound.
