"100 Gecs"  is an American experimental musical duo consisting of Dylan Brady and Laura Les (formerly known as osno1). The two grew up in suburban St. Louis and were involved in the city's electronic music scene. They met at a party in 2012.  Brady lives in downtown Los Angeles and Les is based in Chicago.
The duo works on tracks by sending Logic Pro project files between the two, iterating songs each time. Their music has been called an "anarchic assault on the ears" that " conventional pop tropes in every direction possible", as well as "abrasive, maximalist pop" with "elements of pop punk, nightcore, ska, dubstep, deconstructed club, trance, metal, and happy hardcore all thrown into one big internet blender"
