Q: Question: How many years were The Screamers together before Roessler joined the band? Passage:Paul Roessler was born on August 27, 1958, in New Haven, Connecticut. In 1974, he moved to West Los Angeles where he met and befriended future Germs band members Darby Crash and Pat Smear at University High. After graduating from high school, Roessler went on to study classical music at California State University, Northridge, for a few semesters before leaving in early 1978 to join innovative electropunk band, The Screamers. After two successful years, The Screamers found themselves rapidly disintegrating as a band, causing Roessler to leave in January 1980, and would then go on to play in Nervous Gender with former Germs drummer Don Bolles as well as in Geza X and the Mommymen. After a few months of going between bands, he was recruited by Nina Hagen to join her for an upcoming European tour. After touring Europe and America with Hagen, they recorded Nunsexmonkrock. Before Roessler's second tour with Hagen, Pat Smear from the Germs joined the band. Later, when Smear left the band, Roessler left also. In 1981, he formed the band Twisted Roots with Smear and sister Kira Roessler. During this time, he was playing with 45 Grave, Josie Cotton, DC3 (with Dez Cadena of Black Flag) and Crimony (with Mike Watt) as well. Roessler was also doing sessions with many other bands such as the Dead Kennedys and Saccharine Trust. Roessler has continued to work with Nina Hagen and Josie Cotton. From 1998 to 2011, Roessler worked as the in-house producer at Satellite Park Studio with Geza X. In 2006, Roessler released an autobiographical poetry book entitled Eight Years (Brass Tacks Press, 2006). He continues to write his own music and is currently recording a new album. In 2010, Roessler produced and played keyboards on Nina Hagen's gospel album Personal Jesus (Universal). He has been a member of the Fancy Space People with Don Bolles and Nora Keyes since 2009. In October 2011, they joined the Smashing Pumpkins on their "Other Side of the Kaleidyscope" tour.

Q: Question: Who succeeded Khalid's son as ruler of  the family's stronghold? Passage:Khalid was a member of the Shayban tribe, dominant in the region of Diyar Bakr in the northern Jazira, and third son of Yazid ibn Mazyad al-Shaybani, who served twice as Arab governor (ostikan) of Arminiya (a large province encompassing the whole of Transcaucasia). Khalid served in the same office no less than four times: in 813/814, 828–832, briefly in 841 and again under Caliph al-Wathiq (r. 842–845). In his first tenure, he showed himself conciliatory towards the native Christian population and the nakharar princes, but his second tenure was marked by the brutal suppression of several revolts by local Arab magnates, as well as the harsh treatment of the Christian population. As a result, when his re-appointment to the office was announced in 841, a rebellion broke out, forcing the Abbasid government to recall him immediately. Nevertheless, al-Wathiq assigned Arminiya to Khalid. The latter arrived in the province at the head of an army, and crushed any opposition. He died soon after at Dvin, where he was buried. He was succeeded by his son, Muhammad. His younger son Haytham ibn Khalid ruled in the family's stronghold of Shirvan, and was the first to claim the title of Shirvanshah.
