The guys from P.O. Box have played Jera On Air three times before. The skapunkers are not afraid to throw a good party and this makes them welcome guests in Ysselsteyn. Although the band is from Nancy, France, they have a great international sound. They were clearly inspired by bands such as Mad Caddies and The Suicide Machines. Since 2001 P.O. Box has toured through Europe almost non-stop and made a trip to Japan and Canada. The band released its third studio album "F#RTH#R" in 2014; a record filled with explosive skapunk tracks.
