Ferré was also a talented pianist who recorded several albums of his piano music. On January 3, 1959 he founded the Museo de Arte de Ponce, in his hometown of Ponce. The museum initially displayed 71 paintings from his personal collection and today displays over 3,000 pieces. Among other things, Ferré is credited with having rescued from oblivion the painting "Flaming June" by the Victorian painter Frederic Lord Leighton – purchasing it in 1963, when it was considered "too old fashioned" and getting it prominently displayed at the Museo of Arte de Ponce.
