“Under a Vast Sky” (海阔天空), a monster ballad from the early ‘90s by Hong Kong rock band Beyond, has become the unofficial anthem for Hong Kong’s pro-democracy protests.
The 1993 hit has become the rallying cry for protesters angry over a China ruling that limits political reform in Hong Kong. Nikki Lau, a Hong Kong resident who has participated in the protests for the past three days, said protesters have sung the song nearly 10 times each day.
