Muse are well known for their antics when indulging in some mushrooms.
Most of the sessions for Origin of Symmetry were famously recorded when they were 'shroomed up.
There is a scene in the Hullabaloo Extras, when Dom and Matt were seen in a store with little plastic bags of "Magic Mushrooms", and later, a scene of mushrooms cooking.
It appears that they have cut back in recent years but Matt Bellamy did state in an interview with Q magazine: "The magic mushrooms have made a bit of a comeback recently."
In the same interview with Q, Matt described a recent 'trip' on a bouncy castle at a Las Vegas fancy dress party in which he merged into a Salvador Dali painting. Bellamy said: "Dom had a dog mask on and he ran off into the desert and I ran after him. For a minute I was actually in a Salvador Dali painting. If you look at his painting 'The Elephants', I was the little person at the bottom of those elephants' legs". Matt also claimed that the use of psychedelic mushrooms helps to "open new doorways".
