Less than 24 hours after HTID Australia unveiled the lineup for KLASSIC 2027, a scheduling conflict has forced a notable change to the bill. HSU Events confirmed today, 8th October, 2026, that Brennan Heart will no longer appear at the Sydney Showground event on 23rd January, 2027, following a miscommunication between his management team and HSU that revealed he is already committed to a separate performance in Germany on the same date.

In place of Brennan Heart, HSU has announced two additions that will reshape one of the evening's most anticipated sets. Noisecontrollers steps in to join Wildstylez, with the pairing now billed as "The World of Klassic Madness," while Warface joins the lineup independently under the "Raw Klassics" banner. Both artists bring strong credentials in harder styles, and the additions maintain the event's focus on celebrating genre-defining music across multiple eras and subgenres.

The updated KLASSIC 2027 lineup now features Technoboy x Tuneboy, D-Block and S-Te-Fan x DJ Isaac, Wildstylez x Noisecontrollers, Gammer x Hixxy x Stonebank, and Warface, with Villain returning as host. The overall structure of the event remains unchanged, with the one-night celebration still running at Sydney Showground on 23rd January, 2027.

For those yet to secure their spot, HSU presale tickets go on sale tomorrow, 9th October, 2026, at 12:00pm, with general public tickets following on 10th October, 2026, at 12:00pm, subject to availability. Given the demand that has accompanied every previous HSU Events production, acting quickly on presale access is strongly advised. KLASSIC 2027 has been positioned as a singular, non-repeating event, making it one of the most compelling harder styles occasions Australia has seen in years.
