When I signed up for my ill-fated bass lessons years ago, the first thing my tutor told me was: "Doesn't matter if you can't hear the basslines. What matters is that 'listeners should feel the basslines'. The ground beneath their feet should shake when the bass amp comes on!"
You get his drift?

Bauchklang is incredible! Beats me that a bunch of beatboxers can nail such brilliant basslines/ tracks!
