I think @akabillposters brings up some good points about the need to be a bit sceptic about this. I got really excited about the story and forgot to consider whether it was actually the kid making the music or not.
I think these are his parents: http://www.bucketbrigadetheater.com/about/staff/
They seem to have some experience and talent when it comes to music making and have obviously helped him to some extent. If it turns out they made all the tracks, I’m still excited about the fact that there are parents out there who can whip some nice WUBS together like this.
