Oteri founded Jazz Gunn, (AKA MateMaToot) along with drummer Brannen Temple (Sheena Easton, Kevin Paige, Robben Ford, Eric Johnson), bassist Chris Maresh (Eric Johnson, Abra Moore, Mitch Watkins), Mike Malone (Jimmy Smith) on sax and Chris Tondre on second guitar. In 1999 Jazz Gunn published "Concepts of Mate Ma Toot".
The sound is heavy and sometimes in your face mix of free form improvisation and structured ideas, which weave in and out through a mix of solid grooves and loose free rhythms.
Willie has performed with or supported Brannen Temple, Jazz Gunn (Matematoot), Doobie Brothers, Bob Seger, Lacy J. Dalton, Tunji, Jacob Fred Jazz Oddysey, Neil Young, Roy Hargrove, Karl Denson's Tiny Universe, Chaka Kahn and several others.
