Definition: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Input: Passage: Zappa then formed and toured with smaller groups that variously included Ian Underwood (reeds, keyboards), Ruth Underwood (vibes, marimba), Sal Marquez (trumpet, vocals), Napoleon Murphy Brock (sax, flute and vocals), Bruce Fowler (trombone), Tom Fowler (bass), Chester Thompson (drums), Ralph Humphrey (drums), George Duke (keyboards, vocals), and Jean-Luc Ponty (violin).
By 1973 the Bizarre and Straight labels were discontinued. In their place, Zappa and Cohen created DiscReet Records, also distributed by Warner Bros. Zappa continued a high rate of production through the first half of the 1970s, including the solo album Apostrophe (') (1974), which reached a career-high No. 10 on the Billboard pop album charts helped by the No. 86 chart hit "Don't Eat The Yellow Snow". Other albums from the period are Over-Nite Sensation (1973), which contained several future concert favorites, such as "Dinah-Moe Humm" and "Montana", and the albums Roxy & Elsewhere (1974) and One Size Fits All (1975) which feature ever-changing versions of a band still called the Mothers, and are notable for the tight renditions of highly difficult jazz fusion songs in such pieces as "Inca Roads", "Echidna's Arf (Of You)" and "Be-Bop Tango (Of the Old Jazzmen's Church)". A live recording from 1974, You Can't Do That on Stage Anymore, Vol. 2 (1988), captures "the full spirit and excellence of the 1973–75 band". Zappa released Bongo Fury (1975), which featured a live recording at the Armadillo World Headquarters in Austin from a tour the same year that reunited him with Captain Beefheart for a brief period. They later became estranged for a period of years, but were in contact at the end of Zappa's life.
Output:
What is the name of the label that came after Zappa discontinued his old one in 1973?
