Ian Fraser Kilmister (24 December 1945 – 28 December 2015), better known as Lemmy, was an English singer, songwriter, and musician, best known as the founder, lead singer, bassist, and primary songwriter of the rock band Motörhead.

Lemmy's music was one of the foundations of the heavy metal genre. He was known for his appearance, including his friendly mutton chops; gravelly, raspy singing voice, which was declared "one of the most recognisable voices in rock"; and his way of singing, looking up towards "a towering microphone tilted down into his weather-beaten face". He was also known for his bass playing style, using his Rickenbacker bass to create an "overpowered, distorted rhythmic rumble". Another unique aspect of Lemmy's bass sound is that he often played power chords using growling overdriven Marshall tube bass stacks. Alongside his music career, he also had minor roles and cameos in film and television.
