 To find wider acceptance, some first-generation artists such as Sai Sai Kham Hlaing and Ye Lay mixed hip-hop with pop, and found commercial success.After Acid's breakthrough, a group named "9mm" moved the style of Burmese hip hop to a new level.Although the group's underground music was well known to the youth, most of their songs did not pass the Burmese censor board, and the group never released an own album under 9mm.
