What would it sound like if members from Foo Fighters, Metallica and Iron Maiden all got together for a jam? Well, only the people in attendance at the session know, but fans would like to hear a taste too.

Foo’s drummer Taylor Hawkins along with Metallica bassist Robert Trujillo and Iron Maiden’s Adrian Smith rocked out at a party last week. Eighties metal rocker Howie Simon from Alcatrazz shared the photo on his Instagram, which kicked off fans begging for a listen.

One user commented on the post, “OMG we NEED to hear this!!! Keep it up!!”, while another wrote, “I would pay good money AND travel to see this live”.
