Time Skiffsnine songs are love letters, distress signals,en plein air observations, and relaxation hymns, the collected transmissions of four people who have grown into relationships and parenthood and adult worry. But they are rendered with Animal Collectives singular sense of exploratory wonder. Harmonies so rich you want to skydive through their shared air, textures so fascinating you want to decode their sorcery, rhythms so intricate you want to untangle their sources. Here is Animal Collective’s past two decades, still in search of whats next.
