As news of the death of Motorhead's iconic frontman Lemmy Kilmister makes its way around the world, the many musicians he influenced and counted as friends are expressing their grief on Twitter.

Lemmy died of cancer today (December 28), four days after his 70th birthday. According to the band's statement on Facebook, he had only learned of his diagnosis two days ago, and was at home playing a video game when he passed.

His death at the age of 70 ends one of the truly great rock n' roll lives. In the last few years of his life, his health issues forced Motorhead to cancel numerous shows. But he fought through it as best as he could and gave everything he had. An ultimate road dog, the band ended a European tour two weeks ago, which had its own share of problems. Shortly before they started, they learned of the death of former drummer Phil "Philthy Animal" Taylor. Then, the Paris terrorist attacks happened two days before they were scheduled to perform. Finally, an undisclosed illness to guitarist Phil Campbell saw them cancel three dates. Still, they were about to embark on another European tour on Jan. 23, 2016.

With his traditional onstage introduction of "We are Motorhead and we play rock n' roll," Motorhead's stripped-down, take-no-prisoners approach led to him being one of the few rockers who had credibility in both the punk and metal circles. Take a look below to see what many of those musicians are saying about him.
