From Relix.com( a fairly reliable source to some) : During Santana’s New York stop last night, the guitarist also nodded to his longtime producer, Clive Davis, who helped restore his pop career with 1999’s Supernatural. Also of note, on June 4, as Santana’s tour rolled through Atlanta, Trey Anastasio guested on a sandwich of “Venus” and “Upper Egypt,” as well as a Los Lonely Boys-bolstered version of “Boogie Women.”
