Nils Frahm is one of the contemporary neoclassical composers that, just like many Nordic colleagues (see Ólafur Arnalds), finds his personal compromise between the European music tradition and the modern needs with a careful timbral research based on a combination of electronics (strictly analog) and acoustic (often prepared ad-hoc) instrument. The outcome is extremely introspective and breathtaking, minimalistic in its harmonic architecture, just to let the listener focus on the atmosphere rather than the score itself.

Hammers is a piano solo piece found in Spaces, a 2013 album, based on a harsh ostinato that exploits the harmonic progression with minimum variations. Philip Glass? Steve Reich? Probably.
