Massachusetts metal merchants UNEARTH today officially welcomes KILLSWITCH ENGAGE drummer Justin Foley to the fold for the band's upcoming slot on this summer's Rockstar Energy Drink Mayhem Fest and their European headlining tour (dubbed the Hell On Earth Tour) to follow.

Foley, who also performed on the band's upcoming Darkness In The Light full-length, takes the place of former drummer Derek Kerswill, who parted ways with the band last year due to creative differences.

Comments vocalist Trevor Phipps: "It's great to have Justin on board for Mayhem and Hell On Earth. We really wanted to start this album cycle with Justin behind the kit since he played on and completely slayed the new album. We've been friends for a long time and we recorded an album together, so this just makes sense and it gives us even more to look forward to this summer."

Adds Foley: "I'm really looking forward to playing with some old friends, and spending a summer full of beers and breakdowns!"

Unearth will release their new album, Darkness In The Light, on July 5th via Metal Blade Records. The album was recorded at Zing Studios in Westfield, Massachusetts with producer Adam Dutkiewicz (KILLSWITCH ENGAGE guitarist). The album was mixed by Mark Lewis (THE BLACK DAHLIA MURDER, WHITECHAPEL, DEVILDRIVER, TRIVIUM) from Audiohammer Studios in Sanford, Florida.

Darkness In The Light tracklisting:

'Watch It Burn'

'Ruination Of The Lost'

'Shadows Of The Light'

'Eyes Of Black'

'Last Wish'

'Arise The War Cry'

'Equinox'

'Coming Of The Dark'

'The Fallen'

'Overcome'

'Disillusion'

Check out the first single 'Eyes Of Black' below. Said Phipps of the track: "We chose 'Eyes Of Black' to be the first song heard out of the gate as we feel it represents the 'Unearth sound' and style perfectly and it's simply a hard-hitting, catchy-as-hell song. The lyrics are also in line with many of the albums darker lyrical themes. I'm not speaking for all of the band, but this is my personal favorite on the album and I can't wait to get out there and play it live!"
