I went to this show after getting pitched by the artist (let's be honest, with that title I don't think I really needed a pitch) but after describing the show I said "So Rachel Bloom-esque" and she confirmed "Rachel Bloom meets Nanette" — and that was exactly it.
If you're a fan of either Rachel Bloom or Hannah Gadsby, you'll be a fan of this.
And if you're not, you still might be a fan of this, too.
