To quote the Manic Street Preachers biography by Simon Price 'Everything (A Book About Manic Street Preachers)', "Sean Moore is quite possibly the only person in rock who doesn't take the Manics seriously". He is the most quiet of the Manics, but according to his band mates their "musical driving force". In their early days, he was often mistaken for a girl due to his long hair, naturally effeminate features (as opposed to Nicky Wire and Richey Edwards' arguably more forced androgynism) and small stature. He is the only current member of the Manic Street Preachers who has not released a solo album.
Moore also has a strong interest in motoring, and set the 22nd fastest lap time around the Nürburgring, Germany, in an Audi RS4 in 8 minutes 25 seconds. Manics singer James Dean Bradfield mentioned this before Motown Junk as part of the annual Rock AM Ring festival at the track. Moore is a fan of Michael Schumacher.
