Thirty Seconds to Mars return to The O2 for a headline show on Wednesday 28 April 2027.

Thirty Seconds to Mars have announced their “A Beautiful Lie vs This Is War” tour, a powerful new live experience that brings together two of the band’s most iconic albums for one unforgettable night. For the first time, fans will experience two albums in one night, as the band performs the defining hits from both A Beautiful Lie and This Is War.

In a major moment for longtime listeners, former band member Tomo Miličević will rejoin Jared Leto and Shannon Leto, marking a rare and highly anticipated reunion on stage. Each night will deliver a high-impact, nostalgic performance that bridges past and present. Audiences will be transported back to the moments, memories, and emotions tied to these songs, while a new generation experiences their impact for the first time.

Released in 2005, A Beautiful Lie marked a breakthrough for the band, delivering global anthems like “The Kill” and “From Yesterday.” The album achieved multi-platinum status worldwide, propelled by its cinematic sound, emotional intensity, and genre-defining presence in the 2000s alternative rock landscape. Followed by 2009’s This Is War, the band expanded their sonic scope and global reach even further. The album produced an unprecedented run of hits including “Kings and Queens,” “This Is War,” and “Closer to the Edge,” earning multi-platinum certifications worldwide and reinforcing the band’s global success.

Two decades on, both albums continue to resonate with the same urgency and emotional weight that first connected with listeners, reaffirming their enduring legacy and cultural impact. The 17-date run will take the band across Europe and the UK, beginning April 6, 2027 in Lisbon and hitting major cities including Paris, Milan, Berlin, and London, before concluding May 1, 2027 in Dublin.
