A running joke I find some people around me riffing on is that every genre has its “-core” version. This phenomenon finds perhaps its purest expression in the existence of such actual things as mumblecore and normcore.
In the case of the amen break, the “core” is breakcore. Breakcore artists like Enduser and Venetian Snares sample the amen break even faster and more aggressively than in its native domain of jungle. Consider this jungle track from 1997:
We – Magnesium Flares
With all its verve and springiness, it may seem absurd to describe this as “subdued”. And perhaps that isn’t the correct way of characterizing how it is contrasted with breakcore. Maybe a better way to describe it is to say breakcore is more likely to scare you.
Abelcain – Nox Hymnos
Panacea – Stormbringer
Angerfist – Street Fighter (Bong-Ra Remix)
