In 1999 Mr. Stevens began the Conference Call Quartet, featuring his partner of many years, bassist Joe Fonda, in collaboration with German saxophonist Gebhard Ullmann and George Schuller on drums. This quartet has released 6 cd's, including their latest CD "What About ...???" on the Polish "Nottwo" Record Label (2011)
"The recording, "poetry in motion", by the collective group 'conference call' deserves to be considered as one of the year's best for the simple reason that its balance of thought and emotion, structure and freedom, clarity and abandon, is exquisitely and transparently laid out. regardless of who composed any particular tune, providing a distinctive voice, the group acts as an organic unit, with the total sound becoming more than the sum of its parts." --All About Jazz
