Joining us this week out of Toronto is mastering engineer João Carvalho. João began his mastering career in the mid-1990’s while producing records for many of Canada’s groundbreaking artists of the time, and opened his own studio, João Carvalho Mastering in 2003.

In 2011, to further his passion for the ultimate in audio production, João partnered with three colleagues and opened the doors to Revolution Recording. To date, Joao has worked on over 2000 records, with clients including The Smashing Pumpkins, Alt J, Fun, and Protest the Hero.
