Whilst I find the Fooies great in concert (energetic, look like they want to be there, unlike some who go through the motions) there music is getting a bit stale for mine.
They have the odd song that is catchy but most are short lived radio songs that have been done, they dont seem to have the long lasting classic feel anymore.
I guess you run the risk of changing something your good at to something your not but I havent bought an album from them in a while.
One thing you cant question though is there effort, they continually pump out albums and tour, and every interview with Grohl ive seen he is a real character......I really want to love his music again!
