Proving that no-one is too metal to cuddle with cute puppies, the guys from Slayer and Testament got a visit from Motley Zoo Animal Rescue ahead of their recent show in Seattle, WA.
This led to a gallery of the boys cuddling with cute puppies, not exactly something you see every day.
Soundgarden guitarist Kim Thayil also decided to show up and steal a few cuddles.
The rescue organization noted: "What's better than puppies and metal?! Nothing!!
"We were fortunate to spend Saturday night with Slayer, Testament and Carcass who very much enjoyed hanging out and cuddling our puppies! There's nothing better than tough guys showing their soft sides...
"This was the second time we met Kerry King and Paul Bostaph, but this time we got to meet Tom Araya and Gary Holt as well. They are all huge fans of rescue and our mission, so they were happy to enjoy the puppy time.
"The guys from Testament were awesome too and we heard all about everyone's animals they couldn't wait to get home and see! This tour is almost over so they won't have to wait long!
"There was a special surprise when we Kim Thayil of Soundgarden came up to us backstage and asked to see the puppies! He and his wife were absolutely in love with them as well and they really enjoyed the whole concept and our mission.
"It was a great night, and AWESOME show and we are so appreciative of the generosity of these guys and the crew! Thank you!! Thanks also to Niffer Calderwood Photography for the amazing shots."
