Question: Where any singles released from the album Strings? Passage:In 1990 the band signed with EMI Records and released their debut album, Strings. Their initial experiments with synthesised sounds and rhythms were not immediately recognised, although Strings sold 20,000 copies during its first week after release. Two years later the band released their second album, 2, which included the critically acclaimed single "Sar Kiye Yeh Pahar". The song was first aired on MTV Asia, and led the band to widespread fame. After the release of 2, the quartet disbanded to focus on their studies and careers. In 2000 Maqsood and Kapadia released Duur, which revived the band's popularity, and followed it with Dhaani in 2003. This album included the single "Najane Kyun", which was part of the soundtrack for the Hollywood film Spider-Man 2. Following Junoon and Nusrat Fateh Ali Khan, Strings went to India (where they found remixes of one of their early songs playing in clubs). In 2008 Strings released their fifth album, Koi Aanay Wala Hai, with the singles "Yeh Hai Meri Kahani" and "Aakhri Alvida" (included on the soundtracks for Bollywood's Zinda and Shootout at Lokhandwala). The album was co-produced by Bollywood actor John Abraham, and was successful in Pakistan and India.

Question: Of the musical acts Vixen toured with, which one has been active the longest? Passage:Born in St. Paul, Minnesota, Kuehnemund formed an all-female band known as Genesis in St. Paul in 1971, initially as a quintet under the name Lemon Pepper. Her father Carl served as a roadie during her band's earliest days. Genesis was later renamed Vixen to prevent confusion with the same-named English band before breaking up in 1974. A bandmate of hers during that year was Nancy Shanks. After a six-year hiatus she reformed Vixen and shortly moved her band to Los Angeles in 1981, and, in 1983, singer Janet Gardner joined her. The band gained notice by appearing in the 1984 teen film Hardbodies under the on-screen name Diaper Rash. They were also a quintet at the time. She eventually added Roxy Petrucci on drums and fellow Minnesotan Share Ross, then known as Share Pedersen, on bass, the lineup that signed to EMI Records. They released their self-titled debut, Vixen, in 1988. It was released by Manhattan Records in the U.S. and Canada. The band toured with the Scorpions, Ozzy Osbourne, and Bon Jovi, and appeared in Penelope Spheeris' 1988 film, , although only Gardner, Pedersen, and Petrucci appeared in the film.

Question: What was the combined loss record of Zwolle and De Graafschap the same year that Karlsons had a two-day trial with Wolverhampton Wanderers? Passage:As a youth player Karlsons played for his local club FK Liepājas Metalurgs, being taken to the first team in 1998, at the age of 17. He spent the next six seasons with the club, becoming the second top scorer of the Latvian Higher League in 2003 with 26 goals, completing two hat-tricks during the season. All in all he played 96 matches for his local club, scoring 40 goals. After these bright appearances he had impressed clubs abroad, and in January 2004 Karlsons went on a month-long trial with the Russian Premier League club Shinnik Yaroslavl. Afterwards he signed a three-year contract with them. However, his spell there wasn't as successful as expected and was very short. After just one season, during which he played only 8 league matches without scoring goals, Karlsons returned to the Latvian Higher League, signing with the newly promoted, ambitious club Venta Kuldiga in 2005. However, the club struggled financially and after just five matches had to let some of their players go, including Karlsons, who returned to his hometown club, Liepājas Metalurgs later that year. He spent the next three seasons there, once again showing great performance. He scored a hat-trick in the 2005 season, and he also scored in the Latvian Cup final on 25 September 2005, which Metalurgs lost 2–1 to Venta Kuldīga. Another hat-trick came in the 2006 season, which Karlsons finished as the second top scorer with 14 goals under his belt. In the Latvian Cup he scored a hat-trick in the 6–1 semi-final victory over Dižvanagi Rēzekne and then scored in the final, which the club won 2–1 over Skonto Riga. In December 2006 Karlsons was named the runner-up of the Latvian Player of the Year Award by the Latvian Football Federation behind the winner Aleksandrs Koļinko, who that time was the first-choice keeper for Rubin Kazan in the Russian Premier League. His contract with Metalurgs expired in July 2007 and it was not renewed. Player was then linked with the English Championship club Bristol City, before going on trial with Southampton. In January 2008 he had a two-day trial with Wolverhampton Wanderers. Karlsons then had trials in the Netherlands with Zwolle and De Graafschap,
