Die Band \'Conference Call\' existiert seit 1998 und hat in dieser Zeit mehr als 10 Tourneen in den USA, in Kanada sowie in ganz Europa unternommen sowie vier vielbeachtete CDs veröffentlicht. Die Band geht zurück auf die Zeit als Ullmann und Stevens in Park Slope (Brooklyn) Nachbarn waren, featured ausserdem Stevens\' langjährigen Partner Joe Fonda am Bass und über die Jahre unterschiedliche Schlagzeuger: Matt Wilson, Han Bennink, Gerry Hemingway und George Schuller. Letzterer spielt seit einigen Jahren fest im Quartett. Alle vier Musiker komponieren für Conference Call. Es erklingen ausschliesslich eigene Kompositionen. Über die Jahre hat sich ein einzigartiger Bandsound etabliert bestehend aus Gebhard Ullmanns ungeheuer intensivem und sensiblem Spiel auf verschiedenen Saxofonen sowie der Bassklarinette, der rhythmisch/klanglichen Virtuosität von George Schuller und dem kreativen und fast traumhaften Piano/Bass Zusammenspiel von Joe Fonda und Michael Stevens. Die erste Studio CD mit George Schuller ist 2008 beim portugiesischen Label Clean Feed unter dem Titel \'Poetry In Motion\' erschienen und markiert zugleich das 10-jährige Jubiläum des Quartetts. Sie wurde von Allabout Jazz New York zu einer der besten CDS des Jahres 2008 gekürt. 2010 erschien auf dem polnischen Label NotTwo Records eine neue Live-Doppel-CD unter dem Titel \"What About ....?\" Pianist/Composer Michael Jefry Stevens performs extensively in Europe and North America.
