Question: When did the person die who had a long feud with FDR? Passage:Roosevelt came to office in 1929 as a reform Democrat, but with no overall plan. He tackled official corruption by dismissing Smith's cronies and renamed the New York Public Service Commission. He addressed New York's growing need for power through the development of hydroelectricity on the St. Lawrence River. He reformed the state's prison administration and built a new state prison at Attica. He had a long feud with Robert Moses, the state's most powerful public servant, whom he removed as Secretary of State but kept on as Parks Commissioner and head of urban planning. Moses was replaced with the Bronx's Democratic Boss Edward J. Flynn. When the Wall Street crash in October 1929 ushered in the Great Depression, Roosevelt started a relief system that later became the model for the New Deal's Federal Emergency Relief Administration (FERA). Roosevelt followed President Herbert Hoover's advice and asked the state legislature for $20 million in relief funds, which he spent mainly on public works in the hope of stimulating demand and providing employment. Aid to the unemployed, he said, "must be extended by Government, not as a matter of charity, but as a matter of social duty." In his first term, Roosevelt famously said, "The United States Constitution has proved itself the most marvelously elastic compilation of rules of government ever written." He was referring to the belief he had that the Federal government would need to use more power in order to bring the country out of the Depression.

Question: What music group produced the 2000's album that the UCSD Guardian described as "experimental"? Passage:Critical reaction to "The Gift That Keeps Giving" was generally positive with the New Musical Express rating it as one of the best on parent album Hey Venus!; "[it doesn't so much raise] the bar, as balances it on top of Mount Snowdon" going on to state: "From a foundation of ELO guitar cloud-swells, Gruff's Elvis Costello-in-a-bubblegum-bath voice wraps around tender trombone parps to create the band's most beautiful moment since "Demons". BBC Wales commented on the track's Christmas links, describing "The Gift That Keeps Giving" as a "mellow, mellifluous, slow ode to the joys of the festive season ... lyrically incredibly simple ... brain-bendingly catchy". The Guardian meanwhile, stated that the song "might sound more California than Christmas" but still possesses the "obligatory sleighbells ... shaken throughout". Much was made of the 'retro' nature of the track with Yahoo Music UK claiming that the song is "a pure blue-eyed soul tune, of the sort that Dan Penn and Spooner Oldham used to churn out four decades ago" and The Guardian describing it as a "gorgeous, Bacharach-tinged haze". In contrast the UCSD Guardian described "The Gift That Keeps Giving" as "jazzy" and "lo-fi" and saw it as "a throw-back to 2000's experimental Mwng".
