An all-star lineup of rock and metal musicians has been put together for the new documentary Father of Loud, about Marshall Amps and it's legendary founder, Jim Marshall. Slash, Zakk Wylde, Motorhead's Lemmy Kilmister and Slayer's Kerry King are just a few who gave some of their time to pay tribute to one of rock music's most important figures.

The life of Jim Marshall was a remarkable one. Forever known as the Father of Loud, he completed the first Marshall head in 1962 while running a drum shop. "In 1960 Jim opened a drum shop which soon became a popular haunt for the up and coming rock bands of the time," reads a description on the Father of Loud website. "'All the drummers used to bring their groups in with them, which is how I got to meet guitarists like Pete (Townsend) and Ritchie (Blackmore),' Jim recollected. 'They kept pestering me to stock guitars and amps so I decided to give it a go.' He quickly became aware of the fact his guitar playing customers were all searching for a sound they just couldn’t get from the amps available at the time."

It continues, "After five 'close but no cigar' attempts, the first Marshall head was built in September 1962. Prototype six became the first Marshall and it was placed in the shop window in September 1962. It was named the JTM45 - JTM being an acronym for Jim & Terry Marshall, Terry being Jim’s son. This game changing, all-valve head produced 30 Watts of clean power. The JTM45 was an instant hit due to its aggressive but musical tone, in fact twenty three orders were taken on the very first day it was put out."

Jim's 2012 passing brought the music world into mourning, but the Father of Loud documentary will play a part in keeping Marshall's memory alive. Along with Slash, Zakk Wylde, Lemmy and Kerry King, Billy Gibbons (ZZ Top), Joe Bonnamossa, Joe Satriani, Lzzy Hale (Halestorm), Adrian Vandenberg (Whitesnake), James Lynch (Dropkick Murphys), Joanne Shaw Taylor and Joel O'Keeffe (Airbourne) will all discuss the importance of Marshall in music.
