Problem: Background: Iron Maiden are an English heavy metal band formed in Leyton, East London, in 1975 by bassist and primary songwriter Steve Harris. The band's discography has grown to thirty-eight albums, including sixteen studio albums, twelve live albums, four EPs, and seven compilations. Pioneers of the new wave of British heavy metal, Iron Maiden achieved initial success during the early 1980s. After several line-up changes, the band went on to release a series of UK and US platinum and gold albums, including 1982's The Number of the Beast, 1983's Piece of Mind, 1984's Powerslave, 1985's live release Live
Context: Iron Maiden were formed on Christmas Day in 1975 by bassist Steve Harris shortly after he left his previous group, Smiler. Harris attributes the band's name to a film adaptation of The Man in the Iron Mask from the novel by Alexandre Dumas, the title of which reminded him of the iron maiden torture device. After months of rehearsal, Iron Maiden made their debut at St. Nicks Hall in Poplar on 1 May 1976, before taking up a semi-residency at the Cart and Horses Pub in Maryland Point, Stratford. The original line-up did not last very long, however, with vocalist Paul Day being the first casualty as, according to Harris, he lacked "energy or charisma on stage". He was replaced by Dennis Wilcock, a Kiss fan who used make-up and fake blood during live performances. Wilcock's friend Dave Murray was invited to join, to the dismay of the band's guitarists Dave Sullivan and Terry Rance. Their frustration led Harris to temporarily disband Iron Maiden in 1976, though the group reformed soon after with Murray as the sole guitarist. Steve Harris and Dave Murray remain the band's longest-standing members and have performed on all of their releases. Iron Maiden recruited yet another guitarist in 1977, Bob Sawyer, who was sacked for embarrassing the band on stage by pretending to play guitar with his teeth. Tension ensued again, causing a rift between Murray and Wilcock, who convinced Harris to fire Murray, as well as original drummer Ron Matthews. A new line-up was put together, including future Cutting Crew member Tony Moore on keyboards, Terry Wapram on guitar, and drummer Barry Purkis (better known today as Thunderstick). A bad performance at the Bridgehouse, a pub located in Canning Town, in November 1977 was the line-up's first and only concert and led to Purkis being replaced by Doug Sampson. At the same time, Moore was asked to leave as Harris decided that keyboards did not suit the band's sound. A few months later, Dennis Wilcock decided that he had had enough with the group and left to form his own band, V1, and Dave Murray was immediately reinstated. As he preferred to be the band's sole guitarist, Wapram disapproved of Murray's return and was also dismissed. Steve Harris, Dave Murray and Doug Sampson spent the summer and autumn of 1978 rehearsing while they searched for a singer to complete the band's new line-up. A chance meeting at the Red Lion pub in Leytonstone in November 1978 evolved into a successful audition for vocalist Paul Di'Anno. Steve Harris has stated, "There's sort of a quality in Paul's voice, a raspiness in his voice, or whatever you want to call it, that just gave it this great edge." At this time, Murray would typically act as their sole guitarist, with Harris commenting, "Davey was so good he could do a lot of it on his own. The plan was always to get a second guitarist in, but finding one that could match Davey was really difficult."
Question: Did the end up finding a singer?
Answer: evolved into a successful audition for vocalist Paul Di'Anno.

Problem: Background: Overkill is an American thrash metal band, formed in 1980 in New Jersey. They have gone through many line-up changes, leaving bassist D. D. Verni and lead vocalist Bobby "Blitz" Ellsworth as the only constant members. In addition to Verni and Ellsworth, Overkill's current lineup includes Dave Linsk on lead guitar, Derek Tailer on rhythm guitar and Jason Bittner on drums.
Context: After taking a break, Overkill resurfaced in 2002 with Wrecking Everything, their second full-length live album, recorded at the Paramount Theatre in Asbury Park, New Jersey. The album contained only songs that had not been on Wrecking Your Neck, some simply because they were released on later albums, but also a few early songs from albums such as Taking Over and Under the Influence. The same show was used for Overkill's first ever DVD, Wrecking Everything - An Evening in Asbury Park, also released in 2002. The European tour in June 2002, supporting both Bloodletting and Wrecking Everything saw Blaze and Wicked Mystic opening up for Overkill. During the second to last show of the tour in Nuremberg, Germany, Blitz suffered a stroke on stage and collapsed. For nearly three days, rumors ran rampant, reporting everything from Blitz being in a coma, permanently paralyzed, or even that Blitz had died. Finally, three days later, the band announced that the stroke was very minor and had no lasting consequences, as well as no cause that could be determined by the doctors. Overkill signed to Spitfire Records and entered the studio in late 2002 to record their next studio album, Killbox 13. Produced by the band and Colin Richardson and released in March 2003, the album was actually only their twelfth regular studio album, but the Overkill EP was also counted to achieve the number 13. The album received critical acclaim, combining the "new" Overkill with their raw early style as presented on the debut album Feel the Fire. Touring for the album included a number of European festivals during the summer, and a full European tour followed in November with Seven Witches and After All. The band played without Derek Tailer, who was absent for undisclosed reasons. Nobody was hired to fill in for him, so Overkill toured as a four-piece for the first time since 1990. Tailer was still considered a full member of the band. In late 2004, after a Japanese tour with Death Angel and Flotsam and Jetsam, the band started work on another record in D. D. Verni's own recording studio. The album, ReliXIV, was produced and mixed by the band themselves and released in March 2005. Overkill toured the eastern US in April 2005, and just before they went on a European tour in May, it was announced that Tim Mallare would not take part in this tour. Replacing him for the tour was former Hades drummer Ron Lipnicki. A few weeks later, the band announced that Mallare had left permanently and Lipnicki was his replacement. In the summer of 2005, Overkill organized their first US west coast tour in more than ten years, playing Western Canada to Southern California. The tour was such a success that the band was added to the 2006 Gigantour bill, as second stage headliners, marking Overkill's first nationwide US tour since 1994.
Question: Did they tour after this in 2005?
Answer:
Overkill toured the eastern US in April 2005,
