"Boundless Oceans, Vast Skies" (; lit. "sea wide sky empty") is a song by the Hong Kong rock band Beyond. It was released for their studio album Rock and Roll on 14 May 1993, and remains massively popular. The song is an anthem of Cantonese rock music and one of Beyond's signature songs. In 2022, it became the first Cantonese song to record over 100 million views on YouTube.
It has been adopted for several events in Cantonese-speaking regions, such as the Artistes 512 Fund Raising Campaign for the 2008 Sichuan earthquake, and most prominently as the unofficial anthem of the 2014 Hong Kong protests.
Ka Kui was inspired by his trip to Africa in 1990 (after which he also wrote one of his most popular songs "Amani" ("Peace" in Swahili)). Its themeâÂÂpersonal freedom and the pursuit of dreamsâÂÂflowed from Wong's disillusionment with the music industry. It was written to celebrate the tenth anniversary of the band's formation. However, the band's lead vocalist Wong Ka Kui died on 30 June 1993, around two months after the song's release. It went on to gain critical acclaim and commercial success.
The song has been also translated as "Under a Vast Sky", "Ocean Wide Sky High", "Vast Seas, Clear Skies", "Clear Skies, Vast Ocean", and "Hold On To My Dream".
