Ufomammut

Ufomammut is a power trio from Italy, formed in 1999. They play a mixture of Stoner Rock, Sludge, Post-Metal and Psychedelic Rock.

From their website:
UFOMAMMUT means…
UFO [,ju:ef'ou] abbreviation of U(nidentified) F(lying) O(bject)
MAMMUT ['mæmmoot] italian for mammoth
The entire word "UFOMAMMUT" should be pronounced in the italian way and it sounds something like "oofomammoot"...
