Trip-hop triumvirate Etheric Felines’ latest single, “Buy My Ashes,” quickly establishes a bass-quaking beat. That foreboding sense of authority gives rise to Andrea Bullard’s relentless rhymes that slyly wax and wane between idealistic, personal goals and self-confidence. That desire to achieve, weighed against potential security of abandoning dreams, creates a crisis of conscience. This mindful tension is smoothed over by Katie Ross’ subconscious “You don’t know me” chorus, hovering overhead.
