The hippocampus is the part of brain that houses the short-term memory, although the indie band of the same name from Minnesota are sure to be remembered for a lot longer. Frontman Jake Luppen and co. released the surprising, sophisticated album Landmark in 2017, followed up a year later by the more electronically tinged Bambi. Hippo Campus’ heart is certainly in the right place: they sell special anti-gun violence t-shirts, and the income from their other merch goes to the MeToo movement. Not for nothing did Billboard magazine praise their ‘passionate and heavily female fan base’ – the Pinkpop girl is a big fan too!
