Emerging in the late '90s, Spanish hard rockers Marea unleashed a mix of raspy vocals and chugging guitars inspired by heavy-metal stalwarts like Madrid's Barón Rojo and UK trailblazers Motörhead. Leño, a key act in rock urbano, was a vital source of inspiration—while Marea's taste for flamenco represents the far-reaching influence of singer Camarón de la Isla.
