A post-modern fusion of Baroque fugal structures with rhythmic motifs derived from disco music. The piece is highly distinctive for its synthesis of rigid contrapuntal rules with syncopated, motoric driving rhythms.
At Henle 7 this is a late-advanced work — the technical demands are serious and sustained. The main demands: independent voices that must each sing on their own line; fast passage work that stays light and even at tempo; and fine finger independence within the hand.
Beyond that, expect precise articulation — the difference between crisp and blurred is the piece, and polyrhythms that have to lock together without sounding mechanical.
The main technical hurdle is keeping the fugal subjects articulate while maintaining the high-energy, metronomic drive.
Comparable difficulty and character — good candidates for what to learn next.
A level or two down with the same spirit — ideal if this piece is still out of reach.
Where this piece's skills lead: slightly harder works making similar technical demands.

Disco fugue (Op.73) is rated Henle level 7 of 9 — late advanced repertoire, roughly ABRSM grade 8 and above. In the RCM system it corresponds to about level 10.
You should be comfortable at Henle level 7 — meaning you can already play level 6–7 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
A typical performance of Disco fugue (Op.73) lasts about 6 minutes.
