Coming to the end of a short UK tour which has seen her performing at Ronnie Scotts in London and the Cheltenham Jazz Festival, Macy Gray is visiting the Town Hall with a show that celebrates the 25th anniversary of her debut album, On How Life Is. Since that inaugural record, the Ohio-born 57-year-old Grammy winner has released a further nine studio albums and established a successful film and television career. Indeed, her most recent telly appearance came earlier this year, in series six of The Masked Singer.
