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.

Passage: In October 2010, Joe Atlan started uploading his music to YouTube. In just a few days, one of his piano songs received more than 100,000 views. Since that moment, Atlan has used YouTube as the main way to share his music, projects, and stay in touch with the fans. His videos are a display of musical experimentation, sometimes with a touch of humor, usually combining instruments and sounds with no particular Genre, or making original arrangements from movie soundtracks, such as The Hobbit, Star Wars, or Pirates of the Caribbean. Atlan tends to show virtuoso skills as an entertainment and way to practice, specially using his Roland AX-7 Keytar, which has become his signature instrument. He also shares his piano compositions there and publishes them for free. Joe Atlan's songs are usually instrumental piano tracks with an epic fantasy, oceanic and hopeful atmosphere. His work on YouTube is often featured in digital magazines and music-video websites. In 2013, Atlan was also contacted by the Dubbing and Voice actor who does the official Spanish voices of Morgan Freeman, Ian McKellen among others, to start a project combining Music and Poetry.

question:
Passage: The first archaeological investigation of the site was carried out in 1964. In that year, the site was noted during an archaeological survey of the region directed by Maurits N. van Loon of the Oriental Institute of the University of Chicago, and a small sounding was made. In 1965, a more extensive excavation was carried out, again under the direction of Van Loon. Between 1971 and 1974, work on the site was resumed by a team of the French Centre national de la recherche scientifique (CNRS) directed by Jacques Cauvin. All excavations were part of the larger international – and eventually UNESCO-coordinated – effort to investigate as many archaeological sites as possible in the area that would be flooded by Lake Assad, the reservoir of the Tabqa Dam, which was being built at that time. The filling of Lake Assad eventually led to the flooding of Mureybet in 1976. Although the site is now submerged and no longer accessible, the material that has been retrieved during the excavations continues to generate new research. This material is currently stored at the National Museum of Aleppo and the Institute de Préhistoire Orientale in Jalès-Berrias in France.
