K ris Kross of 2 Dabbeat Ch 'yall is a two-person rap group, which became famous in the early 1990s. Famous song: Jump, 1992 brought RAP to the popular stage with a song "JUMP", and won the championship record for the first time in eight weeks. Chris Cross not only created a new trend of pop music, but also was the main spokesman of youth culture at that time. I still remember when the music video of "JUMP" had a high exposure rate, the streets were full of teenagers who imitated them wearing loose baseball uniforms backwards, wearing oversized pants with elastic belt and wearing baseball caps backwards. Surprisingly, the two singers eloquently reflected their youthful sentiment, musical style and modeling, which attracted worldwide imitation, but they were only 12 years old and 13 years old when they were so popular.
