I don't recall knowing much talent from Belgium, but that doesn't mean there isn't any. Let Lohaus from the countryside of Belgium prove to you that talent currently thrives in the great little western European country.
Mind you, I just got back from Belgium, so I may be a tad biased regarding their beer, chocolate, and waffles, but Lohaus simply adds to the fresh taste still left on my palate. With a sound that might remind you of Alt-J, among other bands, Lohaus has a unique character that is immediately inviting.
Founded in 2014, Lohaus currently has two tracks posted to SoundCloud with a modest 90+ followers. I would say this is a band to watch out for in 2015.
