There are multiple artists called Polio.
1) Polio was the laptop-based offshoot of Peter Wright's solo drone projects between 2000-2003. It was originally conceived as a one-off recording for US label Freedom From, but expanded to eventually issue a total of four albums. The project's aim was to digitally recycle unused and rejected Peter Wright recordings using software and occasional live overdubs.
2) Polio is a heavy math rock band from Southampton, formed in 2011 https://www.facebook.com/polioband Read more on Last.fm
