There are two bands with the name 5050. #1: 5050 is a skate punkrock band hailing from the north of The Netherlands. Think of poppy punkrock played by fast technical punkrockers not unlike Satanic Surfers. They released a demo called 'Slaves of modern kind', but with their new 2006 release 'When the shit hits van' they'll be able to play for a bigger and wider audience. #2: 5050 was a Japanese ska-pop band, who are known for the eighth opening theme to the popular anime One Piece, Jungle P. The band broke up in 2009.
