Whether they are a real sister / brother duo from Berlin is ultimately moot. Drummer Astrid (who brings her own bright red backdrop) is quite magnificent at commanding the stage, while Otto wins the heartstring-tugging vote. They engage us with rock’n’roll comedy, oozing talent and charm – ‘Bananenhaus’, for example, tells us that you just cannot rush the consumption of that famous yellow fruit.

The ongoing sibling rivalry and petty bickering break up the musical focus in the best possible way, and the duo are bizarrely believable, managing to buffoon their way through a set list celebrating everything from vegetarian dinosaurs to their own story as orphaned runaways.

These loveable rogues make apt use of the loop pedal in their avant-garde ‘art rock’, though it isn’t just the instruments that get an outing: if you’re not rushing home to brush a pineapple then you just weren’t paying attention. Die Roten Punkte deliver a pleasant mix of tight lyrics and harmonies, combined with slapstick and something that, in another life, might pass for burlesque.
