Cultural resurgence among Thailand's ethnic minorities is most visible in the area of popular culture. The ethnic Lao culture of the northeast has witnessed a revival in the form of commercialized popular music. Widely heard on Thailand's radio stations today, Mor Lam is a traditional music style rooted in Lao musical traditions and sung in Lao. Mor Lam has undergone a transformation from its folk music origins into a commercialized folk-rock genre Mor Lam stars appear on music shows broadcast on national television, and Mor Lam cassette tapes are sold all over the country. Kandrum music, derived from the ethnic Khmer on Thailand's border with Cambodia, has undergone a similar transformation, and there has even been a revival of popular music sung in the dialect of the South.
