Vivaldi has self-released five records, Revelations, The Speed of Dark, Universal Language, Away with Words: Part 1, and Synapse.

He released his second EP titled The Speed of Dark in 2009 (which saw a re-recording/re-release in August 2016) and uploaded his first play-through of Acid Reign on YouTube shortly thereafter.

Vext was offered record deals however Vivaldi left due to not being ready to sign a contract.

It was announced in 2015 that Away with Words: Part 2, a primarily acoustic release, would be put on hold to focus instead on a full album called Synapse.

Following the events of the 2016 Orlando nightclub shooting, Vivaldi broadcast a six-hour live stream to raise funds for the victims and their families.

Angel organized the "Shred for Australia" Livestream to raise money for the 2020 fires featuring musicians such as Herman Li, Tosin Abasi, Nita Strauss, Michael Angelo Batio, Matt Heafy of Trivium, Cole Rolland, Gus G and more.

[10] Today his influences include Carmen Miranda, Kaki King, Jean-Luc Ponty, Evergrey, Misery Signals, Parkway Drive and Mattias Eklundh.

[13] In 2018 Vivaldi was endorsed by guitar manufacturer Charvel, which made him a seven string variant of their "DK-24" as a signature model.
