As is the case with most good metal songs, a good composition is not characterized by distorted guitars and loud drumming.
A good composition will sound good on any instrument, and even better in an acapella performance.
The Houghtones are an acapella group of London School of Economics & Political Science (LSE). This performance was taken from their winter concert in December 2019 at LSE; and in this video they are singing ‘Engel’ by Rammstein.
