  • verb to let oneself go, begin something in earnest. This phrase was originally a piece of black slang, inspired by ‘get down to business’ (probably first used as a euphemism for beginning sexual activity, then transferred to musical activity). The expression is still heard in a musical context, referring for instance to musicians improvising successfully or to disco dancers ‘letting go’.
