As well as fronting Sleeping With Sirens, Kellin Quinn has mastered the art of the guest appearance better than... well, almost anyone else.
Here, we count down his greatest ever guest vocals. Starting with...
09. PALAYE ROYALE - 'MA CHÉRIE'
We're coming out of the gate strong with this one, and we know it. It's incredible. What more is there to say?
08. AT THE SKYLINES - ‘THE AMAZING ATOM’
While their hyperactive, beatdown-friendly take on metalcore didn’t quite set the world on fire, this Californian crew’s debut album did boast a huge guest turn from Kellin. And that goes a long way.
07. AVION ROE - 'INTO THE REST'
On an album full of sweeping, emotional songs from the Dallas four-piece, this was by far the biggest. That’s due in no small part to Kellin’s incredible vocals... and he even appeared in the video.
06. TOO CLOSE TO TOUCH - 'THE CHASE'
If you’re a Sleeping With Sirens fan, these guys should be on your radar too; the two bands sharing a fair bit of musical DNA. Kellin is an admirer of their dynamic post-hardcore - appearing on this track from debut album ‘Nerve Endings’.
05. MEMPHIS MAY FIRE - 'MILES AWAY'
Kellin actually featured on two different versions of this track: one from ‘Challenger’, one acoustic. Both are pretty, pretty emotional.
04. ONE OK ROCK - 'PAPER PLANES'
Teaming up with the Tokyo superstars, Kellin served up an avalanche of sass here. He and Taka made for a formidable vocal tag-team.
03. GOOD CHARLOTTE 'KEEP SWINGIN''
Good Charlotte and Kellin have been close for a while now, and the Sirens frontman brought his powerhouse vocals to bear once again here. It’s one of the strongest tracks on GC's 2016 comeback album, ‘Youth Authority’.
02. MACHINE GUN KELLY - 'SWING LIFE AWAY'
On paper at least, the idea of MGK and Kellin joining forces for a cover of Rise Against’s tear-jerking ballad didn’t sound like a surefire success. But it turned out to be an emotional, genre-defying triumph, which you can check out right here.
01. PIERCE THE VEIL - 'KING FOR A DAY'
Two incredible vocalists, one huge song. This was unforgettable stuff. "You told me think about it, well I did..."
