What is the deal with Starkid?

I was browsing through Twitter and I saw a tweet that celebrated the 10 year anniversary of Starkid and I thought "Oh cool, I really like Brian Holden's content". And then I saw the comments. They were all talking about how Starkid was really Starkid and Starkid's music (For example Everybody's got an Andy) that featured a lot of Starkid. And I was like "Oh, is Starkid a different artist? I already know Brian Holden's music, so I'll check it out." I read more of the comments and they were all giving shoutouts to Starkid, saying Starkid changed their life. I thought "Wow! Starkid must be a really big deal!" But then I saw a tweet that simply said "We love you Starkid" and I'm like "I'm really Starkid?!"<br><br>So what is Starkid and why is Starkid so important to people? I don't get it.
