Yes. I go to E3 every year. Super fun. I go for a mix of fun and business.
E3, TwitchCon, and PAX are the most popular and meaningful conventions to attend.
Take a look at these resources:

Stephan Groth (Apoptygma Berzerk, Acid Queen, Fairlight Children, Total Transformation) I would say has been my main influence.
In terms of standup I would say I'm a huge fan of John Mulaney, mostly cause of his Tom Jones story.
