The Delfonics

They’re the vocal group that set the plate for the golden era of Philly Soul. Led by brothers William and Wilbert Hart, the Delfonics created an enchanted sound of love and longing, passion and heartbreak. Their first hit single "La-La means I Love You," also announced the arrival of Thom Bell, the influential songwriter and arranger who would go on to produce the group’s first four albums and co-write with William Hart many of their classic songs, including  "Didn’t I (Blow Your Mind This Time)." But after Bell left the group to work with the Stylistics and the Spinners, the Delfonics fortunes dimmed, leading to a breakup of the brothers in 1975.

Still, the Delfonics never truly went away, their sounds frequently sampled by hip hop artists, and famously showcased in the Quentin Tarantino film classic "Jackie Brown." And quietly, both William and Wilbert Hart have continued to record and perform. In this special edition of Unsung, they unveil the long, strange story of this memorable, mysterious group.
