Reynolds 2013, p. 96, "1990 also saw the genesis of a distinctively British rave sound, 'hard core', which decisively broke with the mould of Detroit and Chicago, and ended the dependency on American imports. By 1991 this underground sound – actually a confederacy of hybrid genres and regional styles – was assaulting the mainstream pop charts.". Reynolds, Simon (2013).

Reynolds 2013, pp. 96–97, "Between 1990 and 1993, hardcore in Britain referred by turns to the Northern bleep-and-bass sound of Warp and Unique 3, to the hip-house and ragga-techno sounds of the Shut Up And Dance label, to the anthemic pop-rave of acts like N-Joi and Shades of Rhythm, to Belgian and German brutalist techno, and, finally to the breakbeat-driven furore of hardcore jungle...Influenced by reggae and hip hop, hardcore producers intensified the sub-bass frequencies, used looped breakbeats to funk up house's four-to-the-floor machine-beat, and embraced sampling with deranged glee. Following the lead of the bombastic Belgians and Germans, UK producers deployed riff-like 'stabs' and bursts of glaring noise.". Reynolds, Simon (2013).

Reynolds 2013, p. 120, "On the outskirts of the Top Forty, tracks by Manix, T99, the Hypnotist, Quadrophonia, Ravesignal, A Split Second, Congress and UHF exacerbated the sense of a barbarian horde waiting to overrun the pop citadel. In terms of hit rate, this 'golden age of hardcore' compares with the punk/New Wave period of the late seventies.". Reynolds, Simon (2013).

Reynolds 2013, p. 266, "Back in 1993, when hardcore plunged into the 'darkside', a breakaway faction of DJ-producers like Seduction, Vibes and Slipmatt continued to make celebratory, upful tunes based around hectic breakbeats. By the end of 1994, happy hardcore had coalesced into a scene that operated in parallel with its estranged cousin, jungle.". Reynolds, Simon (2013).
