Sean Costello (April 16, 1979 – April 15, 2008) was an American blues musician, renowned for his fiery guitar playing and soulful singing. He released five critically acclaimed albums before his career was cut short by his sudden death from a drug overdose at the age of 28. Tinsley Ellis called him ‘the most gifted young blues guitarist on the scene... he was a triple threat on guitar, vocals and as a songwriter’.
