Palacios was born in Chicago,[1] growing up in neighboring Maywood, Illinois and Broadview, Illinois.[2] After graduating St. Joseph High School in Westchester, Illinois, Palacios moved to Tallahassee, Florida to attend the Florida A&M University, majoring in music.[2] Later transferring to Columbia College Chicago, Palacios formed the idea for his production team, Da Internz, as a part of a class for his Business and Entrepreneurship degree.[3][4][2] Palacios, along his production team partner Ernest "Tuo" Clark, moved to Los Angeles in mid-2005, spending time between Los Angeles and Chicago while attempting to break into the music industry.[2] During this period, Palacios was hired by Columbia as a professor, teaching specialized classes in hip-hop beat making and music production.[2][1]

The duo's first break was produced six songs on rapper Mims' Guilt in 2009, including the album's lead single "Move (If You Wanna)".[5][6] The duo went on to produce music for hip-hop, R&B and pop musicians, most notably Big Sean's "Dance (A$$)" (2011), Rihanna's "Birthday Cake" (2011), and the group's most commercially successful song, "Anaconda" by Nicki Minaj (2014),[7] who were asked to add additional drums to the song by Minaj.[8]

Palacios decided to start a solo career in 2014, under the moniker Enrique Dragon, releasing his first single Out Here which was later performed by Luke James on the FOX TV Show Star.[9] In 2015, Palacios moved back to Chicago for a reset from entertainment and returned to Columbia College Chicago as the school's first Artist in Residence.[7] During this period, Palacios gave a TEDx talk on finding success at his alma mater in 2016.[3]

In 2016 when he returned to Los Angeles, Palacios became a host for Beats 1 Radio,[7] and in 2018 started work as a co-host of the BET talk show Mancave,[10] as well as restarting his solo career, now under the name KOSINE (pronounced 'Co-sign'), with the song "Your World" featuring JoJo.[11] From 2018, Palacios began producing music for the Fox television series Empire and Star,[12][13] and hosted writers camps for songwriters and producers to develop music for Star.[14] For season 3 of Star, Palacios made his acting debut as recurring character Lil' Dini.[1]

In 2020, Palacios worked together with Idris Elba on the song "Kings", which raised money for MusiCares' COVID-19 Relief Fund,[15] produced Kelly Rowland's comeback single "Coffee",[16] and in September produced the music for a major Joe Biden 2020 presidential campaign commercial.[7]

In May 2021, he released his first debut EP album "Truth Serum" over streaming services along with starring in a 28-minute music video visual album/short film of the same name, loosely depicting his struggles of finding himself after 10 years of success in Hollywood, narrating a powerful message in how he persevered above it all. The short film EP was also co-produced by Marcus Paulk of Moesha fame. The exclusive video release premiered on Revolt TV on May 7, 2021.[17]

Palacios' father was Guatemalan Olympiad Teodoro Palacios, who immigrated to Chicago in 1970.[18] His mother was originally from Panama.[9]
