Polish band Trupa Trupa is a far more complicated picture to draw, as they take to the stage in Ljubliana Castle. Having seen them as a three-piece in January, their usual fourth member added even more complexity to this enigma of a band. A singular type of rock band, that exist in our understanding but also just outside of it, their pained vocals dance with a vibrant rhythmic backdrop, crushing walls of noise and psychedelic pop melodies. When their violence dissipates for calm, they hit heights of engulfing beauty. Every audience I have been in watching Trupa Trupa has left stunned, gasping for more but not fully understanding why – that is a special kind of band.
