Virtuoso accordionist, fiddler and bandleader Sharon Shannon has walked a brave and personal path through traditional Irish music, inventively fusing with reggae rhythms, rock backbeats, and the aching twang of American country and bluegrass. She continues to defy and redefine musical boundaries with her latest album, the stunningly diverse LIBERTANGO. a year's worth of touring recording with Sinead O'Connor has lead Shannon to rediscover the role of female vocalists in her own music, leading to several stirring encounters here. O'Connor guest on two traditional songs, while the much-missed Kirsty McColl delivers the title track, a tango by the great Argentine composer Astor Piazolla.
