The Spontaneous Music Ensemble (SME) was a loose collection of free improvising musicians convened beginning in the mid-1960s by the late South London-based jazz drummer/trumpeter John Stevens and alto and soprano saxophonist Trevor Watts. SME performances and recordings could range from Stevens–Watts duos to gatherings of more than a dozen players.
