Task: Question Generation
Input (English): Passage: In late July 1983, Metallica embarked on the two-month Kill 'Em All for One tour with British co-headliners Raven. The tour name melded the titles of the albums the two bands were promoting: Metallica's Kill 'Em All and Raven's All for One, both released on Megaforce. The two groups met in Zazula's home two days before the tour began, and traveled in the same vehicle throughout the tour with five roadies and sound engineer Whitaker. The tour was set to conclude with three shows in San Francisco, thus Hetfield painted "No Life 'til Frisco" on the Winnebago tour bus. The tour had a few poorly attended gigs, such as a performance at the Cheers club in Babylon, New York, attended by some 50 people. After the conclusion of Kill 'Em All for One in early September, Metallica returned to El Cerrito to work on new material. Seven weeks after the tour ended, Metallica booked a number of performances at Bay Area clubs, the first a Halloween gig at the Keystone in Palo Alto. At the Country Club in Reseda, the group debuted "Fight Fire with Fire" and "Creeping Death", along with an early version of "The Call of Ktulu", then titled "When Hell Freezes Over". Three days later, at a gig at The Stone in San Francisco, Metallica premiered "Ride the Lightning", the title track from the upcoming album. In December, Metallica went on a short tour in the Midwest and eastern United States with a three-man road crew: Whitaker, guitar technician John Marshall, and drum technician Dave Marrs. The concert of January 14, 1984 in Boston was canceled because the band's equipment was stolen the night before.In February, Metallica embarked on its first European trek with Twisted Sister, supporting Venom's Seven Dates of Hell tour. The tour was sponsored by Metallica's UK distributor, Music for Nations, who released the "Jump in the Fire" EP for that occasion. The first show was at the Volkshaus in Zurich on February 3. At the Aardschok Festival in Zwolle on February 11, Metallica played in front of 7,000 people, its largest audience at the time. The tour stretched through countries such as Italy, Germany, France, and Belgium, culminating in two sold-out shows at the Marquee Club in London. After concluding the Seven Dates Of Hell tour, Metallica headed to Sweet Silence Studios in Copenhagen to record its sophomore album Ride the Lightning. By the end of the tour, Kill 'Em All had sold 60,000 copies worldwide and Metallica began to gain international recognition.
On June 8, 2013, at the Orion Festival, billed as the fictional band Dehaan, Metallica played the album in its entirety for the first time ever to mark the 30 year anniversary of the album.
