Listeners of BBC Radio 2 today may have noticed that Ed Miliband has taken over presenting duties of their 12-2pm slot for this week only, and today's show saw him ask 'why does anybody like death metal?'

In order to find out, he interviewed Napalm Death's lead singer Mark 'Barney' Greenway, with Miliband trailing the show by tweeting: "I've been a groupie for SO long, been to the gigs, got the T-shirt, now's my chance to meet Napalm Death in person….tune in from 12."

That show has just aired and now you can listen back to it, including a section in which Miliband was taught how to sing like a death metal frontman by Greenway. Check it out here (from 1 hour, 35 minutes in), and check out a short clip from the show here.
