 Other critics view Motörhead as the first significant exponent of the movement and the first band to fully implement a crossover between punk rock and heavy metal . Their fast music , the renunciation of technical virtuosity in favour of sheer loudness , and their uncompromising attitude were welcomed equally by punks and heavy metal fans . Motörhead were supported by many NWOBHM bands on tour , and they also shared the stage with Lemmy 's friends punk band The Damned . Motörhead 's musical style became very popular during the NWOBHM , making them a fundamental reference for the nascent movement and for musicians of various metal subgenres in the following decades .
