5 Seconds of Summer

5 Seconds of Summer, often shortened to 5SOS, is an Australian pop rock band that formed in 2011. Blending catchy pop hooks with punchy pop-punk energy and rock instrumentation, the group built a massive global fanbase through a mix of self-penned anthems and high-energy live performances. Their sound draws on guitar-driven rock traditions while staying rooted in radio-friendly pop songwriting, giving them broad crossover appeal.

Since their formation, 5 Seconds of Summer has grown from a YouTube cover act into a headlining international touring act, known for evolving their sound across multiple albums while retaining the melodic, hook-laden style that first attracted listeners. Their live shows are typically characterized by sing-along choruses, dynamic stage presence, and a strong connection with their devoted fanbase built over more than a decade together as a band.
