Few drummers have had such an illustrious career as Steve Gadd. While the Grateful Web tends to naturally gravitate towards genre-bending, multifarious players, Gadd’s range of original work and cache of collaborations are strikingly diverse. From Simon and Garfunkle’s famed 1981 Concert in Central Park reunion, to Steely Dan’s legendary recording “Aja,” to more recent stints with Eric Clapton and James Taylor, his session portfolio alone is enough to drool over. But Gadd is much more than the man behind the kit.
