As befits an artist whose own work spans the musical map, Sinéad O'Connor's spark has been ignited by a formidable range of forebears and peers. Along with the sterling singer/songwriters (Bob Dylan, Leonard Cohen) who inflect her forthright lyrics, O'Connor borrows from the lilting rhythms and buoyant spirituality of reggae greats (Bob Marley, Burning Spear) and the grit and anguish of soul and blues.
