Pete’s Ponies of the ‘Pocalypse

Pete's Ponies of the 'Pocalypse was one of the greatest bands you
will never hear on mainstream radio. Besides being prone to
alteration, the Ponies, as their die-hard fans called them, were the
world's first Death Metal Blue Grass band.
The fans started referring to their particular genre as Death Grass.
Pete, the lead singer and double banjo extraordinaire once said of the
moniker in a 2012 interview that, "We really didn't want to label
ourselves any one genre. The label on the other hand wanted something
to file our sound under on iTunes."
Igor, the backup fiddle, tambourine player, and blood splatter
technician, was so inebriated one night that he described their sound
like the four horsemen of the apocalypse playing bluegrass singing
about death, dismemberment, and a deep south revival. From that
drunken comment the press came up with first the Death Metal Blue
Grass comment, and the fans shortened it to Death Grass.
Rumor has it that the band preferred the label Death Grass. It is
also rumored that their third drummer, Ulrick "Bubba" Yorlofski, had
it tattooed across his chest just before his spontaneous combustion in
effigy in Berlin in 2010.
