Input: Consider Input: Question: In what modern day countries did the band of nomads  who visited the Hami Desert live? Passage:Beyond an occasional visit from a band of nomad Mongols, this region of the Pe-shan swelling is entirely uninhabited. And yet it was from this region, according to Grigory Grum-Grshimailo (1889-1890 explorer), that the Yue-chi (Yuezhi), a nomadic people akin to the Tibetans, proceeded when, towards the middle of the 2nd century BC, they moved westwards and settled near Lake Issyk-kul; and from here proceeded also the Shanshani, or people who some two thousand years ago founded the state of Shanshan or Lofi-lan. The ruins of this town were discovered by Sven Hedin in the desert of Lop in 1901. Here, says the Russian explorer, the Huns gathered strength, as also did the Turks (Ch. Tukiu) in the 6th century, and the Uighur tribes and the rulers of the Tangut kingdom. But after Genghis Khan, in the 12th century, drew away the peoples of this region, and no others came to take their place, the country went out of cultivation and eventually became the barren desert it is now. During the Hun time, and probably into the Middle Ages, the present desert was a lush steppe grassland able to support sustainable seasonal nomadic horse husbandry on a large scale.

Input: Consider Input: Question: In what city and state did the music festival take place where DeVotchKa's performance was considered a breakout event? Passage:Originally a backing band for burlesque shows, in their early years DeVotchKa also toured with burlesque performer and model Dita Von Teese. Numerous nationwide tours in support of self-released records earned the band an underground following. Their song "How It Ends" introduced the band to a wider audience after being featured in the trailer for Everything Is Illuminated, in a Gears of War 2 trailer called "The Last Day", and in an episode of Everwood (Season 4). Their performance at the 2006 Bonnaroo music festival was considered a breakout event. In between tours, the band was picked by first time film directors Jonathan Dayton and Valerie Faris to score Little Miss Sunshine, a 2006 film that would go on to garner four Academy Award nominations. DeVotchKa, along with composer Mychael Danna, composed and performed the majority of the music for the film's soundtrack and were nominated for a 2006 Grammy Award for Best Compilation Soundtrack. The main song, "The Winner Is", was also used in a commercial by the French-based environment and energy company Suez and the Dutch pension fund PGGM.
