Because of you Ka Kui
Trailer Reactions
Documentary · Music
A documentary feature celebrating the music, life, and artistic pursuit of Canto rock music legend Wong Ka Kui, whose voice and vision defined the sound of Beyond- the most influential Canto rock band of all time. Featuring rare concert footage, never-before-seen archives of Ka Kui's early years, and unreleased work, this documentary offers an intimate portrait of Wong Ka Kui- not through nostalgia, not as a distant legend, but as he truly was. At its heart is the precious legacy of his character and convictions, one that continues to transcend generations, his music still lifting spirits and inspiring hope today.
