HTID Australia has announced the full lineup for KLASSIC 2027, a one-off harder styles celebration set to take place at Sydney Showground on Saturday, 23rd January, 2027. Running from 4:00pm to midnight, the event promises an uninterrupted journey through the most iconic anthems and legacy tracks the genre has produced, featuring nine artists across four back-to-back sets and hosted by Villain.

The lineup is nothing short of extraordinary for fans of classic hardstyle and hardcore. Technoboy and Tuneboy unite for "OMG 20 Years of Klassics," while D-Block and S-Te-Fan join DJ Isaac for "Klassic Shivers." Wildstylez and Brennan Heart bring their set "Let Me Lose My Klassic Minds," and the HTID Crew of Gammer, Hixxy, and Stonebank close things out with "Best Tunes Ever," a trio collaboration celebrating the organisation's roots.

Tickets are available via HSU presale from 12:00pm on Friday, 9th October, 2026, with general public sales opening 12:00pm Saturday, 10th October, 2026, subject to availability. Pricing begins at $189.00 plus booking fee for HSU presale access. Given that every previous HSU festival has sold out, often within hours, registering for presale access is strongly recommended.

KLASSIC 2027 is positioned as a truly singular event, with HTID emphasising it will not be repeated. For harder styles fans across Australia and beyond, this is a rare opportunity to witness genre legends share the stage in a format built entirely around the music that defined a generation. If history is any guide, tickets will not last long.
