Here is what I’ve found so far.
- Erlang.org Course
- Functional Programming with Erlang
- Erlang Master Class, part 1 (background)
- Erlang Master Class, part 2
- Erlang Master Class, part 3
- Basic Erlang series (13 videos by Simon Thompson)
- extra videos from Kent computing
- Cursor Insight Erlang Tutorial
Some of those YouTube channels have other interesting playlists.
Edit, Nov 2019: I added another playlist.
