Dux was originally released by Trio HLK on their 2018 album Standard Time. It is a complex rhythmic instrumental piece with the drums as the central instrument with contributions from guitar and piano. The rhythm uses complex polyrhythms, where different rhythms are played at different tempos, at the same time. This is often impressive with only 2 different tempos but Rich manages to play several at the same time producing a complexity where it is difficult to count exactly how many are played at the same time. This is one of the most amazing drum performances that you will ever see.
You can follow Rich on his Official Website, on Facebook, on Twitter, on Instagram, and on his YouTube channel. You can buy his music on iTunes as Trio HLK. You can buy Trio HLK's music on Bandcamp.
