The free digital sampler which you can get from http://grandfathermusic.bandcamp.com/ contains 4 songs from the upcoming second album In Human Form. The debut album “Why I'd Try” (2010) was engineered by Steve Albini and was very good. I did never get tired of it. I'm not sure which bands I should compare Grandfather with, but Deftones and System Of a Down are not far away.
This sampler makes me guess that In Human Form will be one of my favorite albums of 2013.
