Artist comparison 'Coasts'

Our artist 'Coats' whom we are using for our music video have a indie/pop genre to their music. I have also been looking at other artists that have similar genres in their music. For example bands and artists such as Smallpools, Saint Raymond and COIN sound the same and fall under the same indie/pop genre. It isn't just their music that makes them similar its also their appearance which make them fall under the same category. They both have a primary audience of 18-25, and have the 'boy-band' look which catalyses themselves for a younger audience.
