Inferno (2004–2005)

On 22 February 2004 Motörhead performed an invitation only concert at the Royal Opera House in Covent Garden, London; at Summer Festivals in South America during May; and also Europe during June, July and August. The band had already spent time in the recording studio, working on their next album, Inferno, which was released on 22 June and was followed by the 'Inferno' tour of Ireland with Class Of Zero for three dates, before being joined by Sepultura and taking it to Great Britain. Some of the London show at the Hammersmith Apollo was filmed for TV as Gene Simmons introduced the extra opening act, The Class – a band made up of school children appearing in his Channel 4 series, Rock School – and Würzel joined as guest musician for "Overkill". The band continued the tour with Sepultura across Europe through the rest of November and December. At the show in Magdeburg, Germany on 4 December Motörhead joined Sepultura on stage during their support slot playing the song "Orgasmatron", in celebration of Sepultura's 20th Anniversary. The show on 7 December at the Philipshalle in Düsseldorf was recorded and later released as the Stage Fright DVD.
Motörhead picked up their first Grammy in the awards of 2005 in the Best Metal Performance category for their cover of Metallica's "Whiplash" on Metallic Attack: The Ultimate Tribute. From March until early May, the band toured the USA, and in June and August were on the '30th Anniversary' tour in Europe. On 22 August, the band were the subject of an hour-long documentary, Live Fast, Die Old, which was aired on Channel 4 as part of The Other Side series of documentaries, filmed by new and established directors. On 20 September, a compilation album containing the band's appearances on BBC Radio 1 and a concert recording from Paris Theatre, London, was released as BBC Live & In-Session. In October, the band toured Europe with Mondo Generator before returning to Great Britain to tour with In Flames and Girlschool in October and November. During the show at the Brixton Academy on 19 November, Lemmy joined Girlschool on stage to play "Please Don't Touch". Motörhead finished the year's tours in December, with two gigs in New Zealand and five in Australia with Mötley Crüe.

In 2006, the band performed a four-date House Of Blues tour in the States in March with Meldrum and from June until early August played at European open-air festivals with some indoor headlining shows. On 28 October, the band performed at The Rock Freakers Ball in Kansas City before heading off to tour Great Britain with Clutch and Crucified Barbara.
