O2 Academy Brixton is one of the most iconic and historic music venues in the United Kingdom, located in the heart of Brixton, South London. Originally opened in 1929 as the Astoria Theatre, the building was designed in an ornate Art Deco style by architect Thomas Somerford and was primarily used as a cinema and theatre. Over the decades, its function evolved, and it eventually became a major live music venue.

Known for its unique sloping floor and grand, proscenium arch, the O2 Academy Brixton can accommodate around 5,000 people, making it one of London's largest non-arena music venues. Since the 1980s, it has gained a reputation as a landmark for both British and international acts, celebrated for its vibrant atmosphere, excellent acoustics, and historical significance within the music industry. It has frequently been recognized in industry awards as one of the best concert venues in the UK.

Although the building has retained much of its original architecture and character, it has undergone several refurbishments to modernize its facilities and improve accessibility, all while preserving its distinctive style. There have been no changes in its location; it has always occupied its prominent position on Stockwell Road, just a short walk from Brixton Underground Station. The venue's ability to attract both up-and-coming talent and world famous artists has cemented its legendary status, with countless memorable gigs and events having taken place within its walls.
