When he's not busy fronting All Time Low, co-writing songs with other artists or just... well, living, Alex Gaskarth is a master of guest appearances.
To celebrate that fact, we're reliving his best ever guest vocals. Brace for bangers...
One Ok Rock -'Jaded'
Two incredible vocalists + a truly great band = this world-class banger. "Jaaaaaaaaaadeeeeeeeed..."
Simple Plan - 'Freaking Me Out'
The Canadian pop-punk veterans recruited Alex for something ridiculously catchy back in 2011.
We Are The In Crowd - 'Kiss Me Again'
Alex even featured in the video for this one, and it was emotional to say the least. No, you're crying...
The Dangerous Summer - 'Disconnect'
Going back 10 years, Alex appeared on this tour de force from the recently-reunited cult heroes.
Yellowcard - 'Telescope'
Not only is Alex is on this one, but so are Tay Jardine of SAINTE / We Are The In Crowd andCassadee Pope. Check out that harmony around the 3:20 mark.
Amber Pacific - 'When I Found You'
We already knew that Alex is a master of 'whoas', but did you know that his 'la la la la' game is strong too? Apparently Amber Pacific did when they asked him to guest on this...
5 Seconds Of Summer - 'Long Way Home'
It's not the most obvious one on this list, but as well as co-writing this song, Alex also provided some pretty damn flawless backing vocals. Because you can't always own the spotlight.
Lindsey Stirling - 'Time To Fall In Love'
Alex teamed up with the American violinist for this slice of gooey Christmas...ness. Dive in:
Sing It Loud - 'No One Can Touch Us'
A relic that time almost forgot. But Rock Sound doesn't forget.
