Tone Mason is a Canadian hip-hop and R&B production team from Toronto, Ontario, composed of Mellenius, Don D, and formerly, Aloysius Brown.
Don D. began his career in the 1990s as a member of underground hip hop group Nefarius.
[1][2] Before the fall of Nefarius, he met Aloysius Brown and Mellenius, and the three acted as "production protégés" for each other.
Don D. thought it would be shameful for their material to go unheard, so they formed Tone Mason.
[2] In 2003, the group produced "Back Where I've Stayed" for Choclair's Juno Award-winning album, Flagrant.
