Edna was a Honey Cone who sang with Holland-Dozier-Holland, and Ray Charles on Let’s Go Get Stoned. Her 1977 solo album is pure class — a luxuriant blend of ballads and dancers, supervised and brilliantly arranged by Greg Perry, her old man. De La Soul, Nas and Talib Kweli all drank from the fountain. Oops! itself is all-time rare-groove murder.
