Lushes are a band born of tensions - between art and math, order and chaos, planning and chance. You can hear it in their songs - taut, twitching art-punk that balance anxiety and elation, often within the space of a few bars. Album opener "Harsh" glides along slowly, feeling like a moody and measured art-rock meditation until you zero in on the words in the chorus: "Harsh on my ears, that's the way I like it."
