‘Flapper That’ sees Diagonal invite EVOL — arch propagators of “computer music for hooligans” — to their own, unique establishment for a proper headshrinker of a session. Since Diagonal’s incarnation, EVOL’s hardcore aesthetic and sense of absurdity has been a key influence on the label and Powell’s DJ sets. In effect, 'Flapper That' marks a knowing gurn of respect between these mutually advanced mentalists. The two-part, 20 minute ‘Flapper That’ may be EVOL’s most "accessible" boffin-style banger to date.
