Bulls is a two-piece band that occasionally features a third musician on drums. The two consistent pieces are Alexander Harrison on guitar and vocals, and Samn Lightning on Bass. When performing as a duo, the band is set up to deliver an acoustic show. When a drummer is involved, it takes the form of a Blues-rock power trio. Influenced by Joe Bonamassa, Led Zeppelin, Audioslave and Warren Haynes, Bulls delivers a tasteful mix of covers and originals.
