LEROI MOORE 1961-2008
08/19/2008
We are deeply saddened that LeRoi Moore, saxophonist and founding member of Dave Matthews Band, died unexpectedly Tuesday afternoon, August 19, 2008, at Hollywood Presbyterian Medical Center in Los Angeles from sudden complications stemming from his June ATV accident on his farm near Charlottesville, Virginia. LeRoi had recently returned to his Los Angeles home to begin an intensive physical rehabilitation program.
Peace
