Diego I. Trujillo De León, artistically known as Onesided was born in San Juan, Puerto Rico on March 24th, 2001. He grew up in Río Grande and at a very early age developed an interest in music. At around 10 years old he began practicing guitar. When he was just 13 he began dabbling into music production with a few of his classmates. They all learned through the internet and had reunions at Diego’s house just to make music. As the years passed he learned piano and ukulele as well as how to use the Launchpad Pro and other midi controllers. At 18 years old he started his bachelor’s degree in music at the University of Puerto Rico.
