By day he?s a crime scene snapper, but at the weekend he sheds his white boiler suit, dons a different sort of death mask and takes photographs of another kind altogether. Meet Frank. Okay, he doesn?t actually wear a mask at music festivals, but Team Sonisphere?s newest recruit does live a sort of Batman double life.

Employed by the Swedish CSI department to photograph crime scenes, he?s been shooting festivals over the summer at Hultsfred Park for the past nine years. One minute he?s being kicked in the head by Pete Doherty and falling under the main stage, the next he?s taking pictures of murder scenes.

?There are not so many murders, maybe two or three a year, but they?re actually looking for a dead body right now in a lake north of Stockholm,? Frank explains. So, is there any chance if they find it that they?ll have to helicopter you out of here A-Team style?

?I hope not, I need to shoot Metallica first.?
