Lee Minhyuk drops 'TEMPERATURE' and posts "I'm pumpin' adrenaline" after Waterbomb stage

Lee Minhyuk (이민혁, 35) of BTOB released his new solo single album TEMPERATURE on July 15. "I'm pumpin' adrenaline," he posted afterward.

The caption came right after his Waterbomb festival stage. TEMPERATURE runs on a temperature concept—songs shift from cold tension into heat, mapping emotional changes across the tracklist. Minhyuk wrote and composed every song.

The album arrives at the end of a grueling tour schedule. His solo run, 2026 LEE MINHYUK(HUTA) EUROPE TOUR 'HOOK - WHO : KING', kicked off with a Seoul concert in September 2025, then moved through Tokyo, Taipei, and Bangkok before hitting five European cities in February: Paris, Berlin, Warsaw, Madrid, and London. First European solo tour.

Minhyuk is BTOB's main rapper and main dancer. The group—Seo Eun-kwang, Lee Minhyuk, Lee Chang-sub, Lim Hyun-sik, Peniel, Yook Sung-jae—debuted in 2012 with Insane (비밀) and dropped mini album 13 BTODAY in 2025. Before he was a trainee, Minhyuk was already in the indie hip-hop world under the name Huta, which became his solo alias when he officially debuted as a solo artist with full-length HUTAZONE in 2019. He's also hosted Kiss the Radio.

(The Waterbomb-to-studio pipeline is very much his thing at this point.)
