The Popscene concert at Rickshaw Stop on Tuesday night was one of those rare shows that was very surprising (in a good way). Danish singer-songwriter MØ (Karen Marie Ørsted) headlined the night that featured Swedish singer-songwriter Erik Hassle supporting, and both put on stellar performances, with awesome bookend DJ sets by Aaron Axelsen. Candidly, I was not familiar with either of these young artists until recently, and I would mark the night as one of the best concerts I’ve attended so far in 2014. MØ and Erik Hassle should be on the pop culture watch list as ones to expect big things from in the future.
