This singer/artist reminds me a bit of "Npav Ntsuab" 15-20 years ago the latter's creative spirit of using a "sacred" Hmong ritualistic song ("Hu Plig") as a pop culture song.
And for Maim Lis, I guess he's a Lao Hmong?, it's natural to use Lao's mor-lam rhythmic music for this goofy but exquisitely good song... about traditional Hmong life up in the mountains...
