A classic Hmong song that continues to inspire new generations of musicians and music fans. It's iconic status provides a good example of how what is usually consider popular music can take on a "traditional" character over time.
From what I have been able to piece together, it was written by the prolific Lis Pov (Paul Ly/Lee Pao) currently of the Pheej Ywg Band (website). The earliest version I'm aware of is by the Kaab Nqausvas band with singer Vaaj Ntxawg, but I'm not sure of the date. This version is also available on the "Kaab Nqausvas Best Collection" album, which contains songs from their four previous albums. Information about Kaab Nqausvas is difficult to come by, but I'll post again as I learn more.
The Kaab Nqausvas albums are for sale at Long Chang (LoobCeeb) Entertainment
