XO's sophomore album. Shoegaze purveyors DKFM wrote "Wonder is a heavier affair. The harmonies are shaded more darkly, the epic riffs more often set to minor chords, without losing the soul of what makes XO a special effort. They’ve lost none of their tuneful sensibility, but it is surely updated for a more confrontational era. Singles like “Wonder” and “TV You” are by turns more world-weary and rejecting the chaos of the modern era."
