Pretty much copy/pasting my list from last year:
Matt Mercer
Marisha Ray
Liam O'Brien
Laura Baily
Travis Willingham
Ashley Johnson
Talisin Jaffe
Mamoru Miyano
Christopher Wehkamp
Dave Trosko
It would be amazing if we could get the Final Fantasy Orchestra again. The Samurai Champloo tribute concert was lit. They really nailed it last two years with music guests. I'm excited to see what/if there will be another concert this year.
