Dylan Minnette -- best known for his role as Clay on the hit Netflix show "13 Reasons Why" -- is pretty much the opposite of his character in real life ... at least when he's jamming on stage.
The 21-year-old actor is also a musician, and his band, Wallows, performed at the El Rey Theatre in L.A. Friday night. Check out Clay -- er, Dylan -- shredding on guitar and singing his heart out.
He even throws in some head banging.
If you're not a '13 Reasons' fan, you might recognize Dylan from a few other hit shows -- like "Scandal" or "Lost" -- or movies like "Don't Breathe" and "Goosebumps."
Or maybe you've seen him rock before ... he's actually been playing for years!
