Motorhead is, in my mind, an indoors band. The only good outdoors performance I ever heard from them in recent years was Rock am Ring in 2004, and even that wasn't perfect. Motorhead's approach to sound is best suited to a reasonably-sized indoor environment, not so small that the volume just kills everything, but not so big that the sound is travelling too far. Festival mixer operators never do the band justice, either the drums sound crap, the guitar and bass blend or the guitar is just buried except for solos, or there's so much white noise that it ruins it, especially if the recordings haven't been laboured over.
