Metalcore veterans As I Lay Dying are currently on tour throughout the US in support of their comeback album Shaped by Fire, which dropped a couple of weeks ago, and some new fan-shot footage has emerged online of August Burns Red vocalist Jake Luhrs jumping on stage with the band to provide his powerful voice for the new track 'Redefined'.
Luhrs is a long-time friend of Lambesis, and voiced his support for Tim following release from prison for hiring a hitman in an attempt to murder his wife.
This isn't the first time that the ABR frontman has jumped on stage with As I Lay Dying either - here's also footage from way back in 2008 of the two (much skinnier versions) doing vocals together for 'The Sound of Truth':
