Maybe the following passage from rockandrollreport.com charactrizes the music most clearly:

'I have always maintained that rock and roll is a global phenomena and you have to go no further than Russian band Llanfair P.G. to prove this point. A primitive and wild psychedelic punk band, Llanfair P.G. just go to show that rock and roll is a universal language. Check out their full length MP3 downloads at Download.com. I just think this is so cool and their tunes are great to boot!'
