Question: How long was Frank Pick the general manager? Passage:Through his involvement with the Design and Industries Association Holden met Frank Pick, general manager of the Underground Electric Railways Company of London (UERL). Holden at the time had no experience in designing for transport, but this would change through his collaboration with Pick. In 1923, Pick commissioned Holden to design a façade for a side entrance at Westminster Underground station. This was followed in 1924 with an appointment to design the UERL's pavilion for the British Empire Exhibition. Also in 1924, Pick commissioned Holden to design seven new stations in south London for the extension of the City and South London Railway (now part of the Northern line) from Clapham Common to Morden. The designs replaced a set by the UERL's own architect, Stanley Heaps, which Pick had found unsatisfactory. The designs reflect the simple modernist style he was using in France for the war cemeteries; double-height ticket halls are clad in plain Portland stone framing a glazed screen, each adapted to suit the street corner sites of most of the stations. The screens feature the Underground roundel made up in coloured glass panels and are divided by stone columns surmounted by capitals formed as a three-dimensional version of the roundel. Holden also advised Heaps on new façades for a number of the existing stations on the line and produced the design for a new entrance at Bond Street station on the Central London Railway.

Question: In what city was the concert film by The Band filmed? Passage:In 2003, Minnesota-raised singer, writer, and guitarist Craig Finn and New York City bartender and bassist Galen Polivka began talking about starting a band. Finn and lead guitarist Tad Kubler (both formerly of Lifter Puller) developed the idea of The Hold Steady when, while watching The Band concert film The Last Waltz, Finn asked Kubler, "Dude, why aren't there any bands like this anymore?" The Hold Steady's 2004 debut album Almost Killed Me, released on Frenchkiss Records, was a sleeper hit among music critics, reaching No. 31 in the Pazz & Jop critics poll that year, an achievement which Finn described as "like being nominated for an Oscar or something." In May 2005, they were the first rock band to grace the front page of The Village Voice in 15 years . They were Blender's 2006 "Band of the Year".
