Question: Which state is Albert P. Laning a Senator for? Passage:The caucus of Democratic State legislators met on January 15, State Senator Albert P. Laning, of Buffalo, presided. All but one of the legislators were present, only Assemblyman John M. Roscoe, of Schoharie County, was sick. The caucus nominated Francis Kernan for the U.S. Senate. Kernan had been the Democratic/Liberal Republican candidate for Governor in November 1872 but had been defeated by John Adams Dix. Now Kernan was the choice of Tammany boss John Kelly who had succeeded the corrupt William M. Tweed. Kelly was opposed by John C. Jacobs, who proposed Ex-State Senator Henry C. Murphy, Jacobs's predecessor from the 3rd District, and the Democratic candidate who had lost the U.S. Senate elections in 1867 and 1869 when the Democrats were the minority. Kelly stood firm in his intention to dominate the Democratic Party, and had the caucus nomination made by viva voce vote instead of the more traditional secret ballot. Jacobs and Murphy had expected to get votes from many legislators who would not dare to cross Kelly openly, but had to abandon their hopes when the secret ballot was voted down 74 to 13.

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.
