The Shells were an American doo-wop ensemble active in the late 1950s and early 1960s. The group, led by Nathaniel "Little Nate" Bouknight, was known for its smooth harmonies and soulful ballads, exemplified in their biggest hit, "Baby Oh Baby". Although the Shells had a short-lived career, their distinctive sound made a significant contribution to the doo-wop genre. Their music continues to be appreciated by enthusiasts of vintage pop and rhythm & blues.
