There are quite a few artists with alter egos for when they are doing something a bit different to what they’re known for. Paul McCartney as The Fireman, John Lurie of The Lounge Lizards as The Legendary Marvin Pontiac, Phil Collins’ jazz-prog venture Brand X, Anna Meredith’s twin careers as orchestral composer and electronic musician, Jim Mullen as jazz guitarist and his continuing membership of funksters Kokomo. One I discovered just today, rising jazz guitarist star Shirley Tetteh has also recorded some left-field pop as Nardeydey. I expect you lot could name a few more alter egoists.
