The Carboniferous is a geologic period and system that extends from the end of the Devonian Period, about 359.2 ± 2.5 Mya (million years ago), to the beginning of the Permian Period, about 299.0 ± 0.8 Mya (ICS, 2004). The name 'Carboniferous', which means "coal-bearing" and derives from the Latin words carbo (coal) and ferre (to carry), was coined by geologists, William Conybeare and William Phillips in 1822. Based on a study of the British rock succession, it was the first of the modern 'system' names to be employed, and reflects the fact that many coal beds were formed globally during this time. The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian and the later Pennsylvanian.

Terrestrial life was well established by the Carboniferous period. Amphibians were the dominant land vertebrates, of which one branch would eventually evolve into reptiles, the first fully terrestrial vertebrates. Arthropods were also very common, and many (such as Meganeura), were much larger than those of today. Vast swathes of forest covered the land, which would eventually be laid down and become the coal beds characteristic of the Carboniferous system. A minor marine and terrestrial extinction event occurred in the middle of the period, caused by a change in climate. The latter half of the period experienced glaciations, low sea level, and mountain building.

Michael Allan "Mike" Patton (born January 27, 1968) is an American singer-songwriter, multi-instrumentalist, producer, and actor, best known as the lead singer of the experimental rock/alternative metal band Faith No More. He was also the founder and lead singer of Mr. Bungle, and has played with Tomahawk, Fantômas, Lovage, The Dillinger Escape Plan, and Peeping Tom.

Known for his eclectic influences and experimental projects, Patton has earned critical praise for his diverse vocalization. He has many producer or co-producer credits with artists such as John Zorn, Sepultura, Melvins, Melt-Banana, and Kool Keith. He co-founded Ipecac Recordings with Greg Werckman in 1999, and has run the label since.

Patton was born and raised in Eureka, California, where he formed Mr. Bungle, with Trey Spruance and Trevor Dunn, in 1984. During the late '80s Mr Bungle recorded the cassette-only recordings, The Raging Wrath of the Easter Bunny, Goddammit I Love America, Bowel of Chiley and OU818, featuring tracks that would later be included on their first Warner Brothers album.
