There's another CLIENT Sarah Blackwood, the singer from Dubstar and Client. SARAH BLACKWOOD grew up listening to her father’s rock and roll record collection. When she was twelve years old, her father handed her an acoustic guitar, taught her the basics and the rest, as they say, is history. Her style is influenced by old country and rock music. She’s a sweetheart with an acoustic guitar singing about love, demons she has faced, and different times in her life that have brought her down.
