Eavis was responding to criticism that the heavy metal band does not fit in with Glastonbury’s mainstream image.
“There’s no other band in the whole history of the festival that has been so keen to play, they will do the best set of their lives here,” said Eavis.
Metallica’s Glastonbury debut is the first top slot for a metal band.
“We have been going for so long that people don’t expect us to put on a heavy metal band,” Eavis said.
“We had Rage Against The Machine and we have had lots of fairly heavy metal bands in the past but this is not a typical headline.
“We usually have bands like Radiohead, Coldplay and U2, the Rolling Stones, but I am really looking forward to them.”
