Gaston are a quintet from Berlin. They set out as a trio with two basses and a drum kit. Today the line-up is augmented: There’s a vibraphone, there are guitars and sometimes they make use of brass instruments and samples. Their pieces are instrumental and at times rather intricate, therefore the exhausted and by now almost fading term ‘postrock’ comes into mind. Jazz has surely been influencing Gaston. It remains hard to tell how deeply they are really rooted in musical history.
