California's metallic hardcore titans Lionheart are back and hitting harder than ever with their brand-new single "Bulletproof" — a ferocious statement track that marks the beginning of the next chapter for the band. Groove-heavy, razor-sharp, and fueled by the Oakland outfit's trademark intensity, "Bulletproof" captures everything that has made Lionheart one of the most dominant forces in modern hardcore: Pure aggression, anthemic gang-shouts, and a swagger that could only come from the West Coast.

The release of "Bulletproof" also kicks off the official pre-orders for Lionheart's new album Valley of Death II, set for release on January 9 via Arising Empire.

Serving as the sequel to their 2019 record Valley of Death, the new album promises to be heavier, darker, and even more unrelenting.

Now, after officially re-signing with Arising Empire, Lionheart are charging into their next era with renewed force. Their return to Europe in January 2026 for a massive headline tour — joined by Madball, Gideon, and Slope — will showcase exactly why this new chapter with Arising Empire marks a decisive and powerful step forward.
