“Spiral” is the latest track from Norwegian super producer Todd Terje, and it couldn’t be titled more perfectly. Spinning and twisting through four-and-a-half minutes of light, airy grooves, the sunny single is a dizzying, nu-disco achievement. This year, Terje lent his expertise to Franz Ferdinand’s Right Thoughts, Right Words, Right Actions. Now, his own full-length is set to be released this March. “Spiral” is an auspicious start, overflowing with warmth even on a cold winter’s night.
