Term for this condition - artist

Factual Questions
1

I came across a word, or term for when a person picks up a new art form and is highly prolific. There’s an initial phase where they produce a ton of work - an outpouring of everything they had bottled up that the new art (painting, writing, music) has given vent to.

However I can’t find this word to save my life.

The mental giants over at reddit word-smith volunteered such gems as:
…Diarrhea?
…Vomiting?

Hoping that someone on this forum can cough up the term and give my obsessive-compulsive mind (and my google-fingers) a much needed rest!

Thanks
