The origins for the reunion go back several years, when Schon suggested that he and Carlos Santana record together. Santana liked the idea but went one better, proposing that they recruit Rolie, Shrieve and Carabello for what would be called "Santana IV". After initial writing sessions and rehearsals took place in 2013, the group recorded throughout 2014 and 2015, amassing 16 new tracks that combined all their signature elements – Afro-Latin rhythms, soaring vocals, electrifying blues-psychedelic guitar solos, and irrepressible jubilant percussion work.
