September's been performing at "Så Mycket Bättre", a Swedish TV show broadcasted on TV4.
In the show, Swedish artists cover songs of each other. The songs sung by Petra can be viewed down here! Mikrofonkåt is available in the Swedish iTunes store and Spotify.
In the latest episode (week 6) September's songs have been covered. Click here to watch those covers!
There's one more cover to come (week 7). When the show's finished, a CD will be released. No info on this CD has been published, but it's unlikely all tracks will be featured. Since Mikrofonkåt has been released on iTunes and Spotify, it's likely it'll be included.
