OPETH frontman Mikael Ã…kerfeldt and ENTOMBED's recently departed guitarist Uffe Cederlund openly admit to owing a musical debt to VOIVOD guitarist Denis "Piggy" D'Amour, who passed away on August 26, 2005.
Black Sabbath's Tony Iommi, considered the most important pioneer of heavy metal guitar, achieved his signature slow, heavy sound partially as a result of a factory accident in which the tips of his middle and ring fingers were severed. Iommi fashioned thimble-like prosthetics and relearned the instrument.
