Powerful to say the least, Linnea Jonsson's striking voice sailed elegantly above the Northern Soul-influenced indie pop of Those Dancing Days.

With two members yet to finish their secondary education, and the other three not long out of uniform themselves, the maturity of this Swedish quintet was revealed by onstage giggling when mistakes were made mid-set.

The initial praise that surrounded their eponymous debut single carried the girls on a wave of media attention, and deservedly so. With seriously infectious keys and more energy than EDF, it was by far the highlight of the show. It's this glistening pop that makes up the blueprint for their sound, sadly casting a shadow over the majority of the rest of their set. All too often the songs were formulaic, leaving little or no room for surprises.

Support came from inspired French duo John and Jehn, whose grubby post-punk was a curious but welcome match for the sugar-coated songs of their headliner. Even though they played to a backing track with only 25 minutes to impress, the sultry couple combined simple organs with skewed guitar that gave a necessary edge to the bill.
