is there more than one group called the klaxons? when i was downloading them i got a bunch of the klaxons i know of's electronica type stuff and then i got a bunch of polka music
Apparently so during the 80s - http://rateyourmusic.com/artist/the_klaxons - but I don't know if they are the other band you've found. It could just be people (doing what is often the case on filesharing networks) putting the wrong name on songs.
that is them, they're good but i noticed that several songs were really different
