Alex is a founding member of Incubus and the former bassist. After enjoying over a decade of success with the band he went onto other projects.
In September 2013, Alex and former bandmate Jose Pasillas II (current drummer and founder member of incubus), along with former Pharcyde MC Slimkid3 and Jurassic 5’s DJ Nu-Mark, released a new song and music video titled "Picture Perfect Phantasy" inspired by Ubisoft’s ‘Rayman Legends’ video game. They are performing under the name '4 Player Co-Op' and combine funk, rock and hip-hop.
Katunich has had involvement with Incubus & Picture Perfect Phantasy. "Picture Perfect Phantasy" is the first time that Alex and Jose have recorded together since Incubus’ 2001 multi-platinum release Morning View.
