Research into garage bands and how they're filmed

I've been looking at a few videos that have been filmed in a garage and had a look at how they were filmed. There a few shots in the wayne's world clip were there is close ups of the guitars and then their faces when they sing. It looks like its been filmed on a hand held camera and looks quite unprofessional but it gives a more of 'garage band' feel to it. In the Weezer video you can see someone putting things in the washing machine in the background which again makes it seem unprofessional but gives it the garage band look that we want to go for.
