Few could make an electric guitar squeal and sing like this Belfast-born blues rocker, who also possessed a strong, raspy singing voice of his own. His work spans decades and genres, from the fervent '70s rock of Skid Row and Thin Lizzy to his solo career that featured searing metal in the '80s before reverting to his blues roots in the '90s, adding his distinctively soaring lead lines and controlled feedback while trading licks with the likes of Albert King and Albert Collins.
