Mateo Arias, better known as ¿Téo? (formerly T.O), is a Colombian-American actor, musician, singer and record producer. He is also one of the founding members of the MSFTSrep creative collective alongside his older brother Moisés Arias and longtime friend Jaden Smith.

He started making music for fun and posting it on his SoundCloud since he was 17 years old. In October 2014, he released his debut instrumental single Eclipse. Later that year, he released more music including Jaden’s Prakruti, which was completely produced and engineered by him.

In early 2015, he released Enlightened Now (in which he appeared singing for the first time ever) as a part of his debut EP entitled Divine Intoxication.

In June 4, 2016, he released Selfless-ish which is his most successful song to date, but it wasn’t until August 2017 that he decided to take music serious and released Uno Dos, which was the lead single for his eponymous debut studio album, ¿Téo?, which was released on September next year.
