Input: Consider Input: Question: What year did Vaughn's producer form hiw own label after leaving Mercury? Passage:In 1971, Bob Shad, who had worked with her as producer at Mercury, asked her to record for his label, Mainstream, which he had founded after leaving Mercury. Breaking a four-year hiatus, Vaughan signed a contract with Mainstream and returned to the studio for A Time in My Life, a step away from jazz into pop music with songs by Bob Dylan, John Lennon, and Marvin Gaye arranged by Ernie Wilkins. She didn't complain about this eclectic change in direction, but she chose the material for her next album after admiring the work of Michel Legrand. He conducted an orchestra of over one hundred musicians for Sarah Vaughan with Michel Legrand, an album of compositions by Legrand with lyrics by Alan and Marilyn Bergman. The songs brought some of the musicians to tears during the sessions. But Shad wanted a hit, and the album yielded none. She sang a version of the pop hit "Rainy Days and Mondays" by the Carpenters for Feelin' Good. This was followed by Live in Japan, her first live album since 1963. Sarah Vaughan and the Jimmy Rowles Quintet (1974) was more experimental, containing free improvisation and some unconventional scatting.

Input: Consider Input: Question: When was Madonna's fifth live album released? Passage:On March 1, 2015, Madonna performed the song for the first time on Italian TV show, Che tempo che fa, along with "Ghosttown", the album's second single. An episode featuring her appearance was aired on March 8. For the performance of "Devil Pray", Madonna wore "an extravagant black robe and various rosaries." A writer for Yahoo! noticed that both performances were warmly received by the audience, while Lionel Nicaise appreciated that Madonna put more emphasis on the melodies and her vocals during the performance, rather than costumes and stage props. Bianca Grace of Idolator noted that the performance "will have you repenting your weekend sins, as the singer emotionally sings the tune." "Devil Pray" was performed on Madonna's 2015–16 Rebel Heart Tour. Following the Last Supper-themed mashup performance of "Holy Water" and "Vogue", Madonna climbed down to the center stage to perform "Devil Pray"; during the performance she straddled one of her male dancers, who was dressed as a priest, and engaged in a dance-off with other dancers. Jordan Zivitz from the Montreal Gazette said that she found the performance to be "challenging". Previous to this the song was also used for promotional videos related to the tour's rehearsals and dancer interviews. The performance of "Devil Pray" at the March 19–20, 2016 shows in Sydney's Allphones Arena was recorded and released in Madonna's fifth live album, Rebel Heart Tour.
