One of the most openly political forces in Aussie hip-hop, The Herd captured the jubilation of the long-suffering left with “The King Is Dead,” their send-off for Prime Minister John Howard. Even better, they made a head-nodding sing-along refrain out of an earnest call for change. Elsewhere, Summerland further crystallizes their trademark trick of grafting pointed commentary to snappy tunes like “Toorali” and the horn-kicked “2020.” And their supergroup setup means we get the accumulated talents of Urthboy, Ozi Batla, and Jane Tyrrell—all accomplished solo artists—in full effect.
