AllStar, a Hong Kong Cantopop boy band, was formed in 2009 through the singing contest Star Hunt held by Kingdom C. The group consists of King Wu, Kenny Chan, Andy Leung, and Jase Ho. They gained early popularity busking on Sai Yeung Choi Street South before debuting with the album Make It Happen in 2010. Their breakthrough came with the release of "Tin Tai" (天梯), which became their signature song and helped them win multiple awards, including four Ultimate Song Chart Awards for Group of the Year. In 2011, C AllStar signed with Media Asia Music and released 新預言書 (first edition). They continued to release albums, including Cantopopsibility in 2013. In 2017, they announced a hiatus, but reunited in 2021 with the release of the single "集合吧！地球保衛隊" (“Together We Strive for a Better World”), which topped all five major Hong Kong music charts.
