PROBLEM: Passage: There is a great deal written in music history books about the period of artistic experimentalism after World War II in Europe and the United States. Much like the period in France after the Franco-Prussian War (Impressionism) and in the late 19th century, the pre/post World War I period of (Expressionism), the post World War I period of Modernism was no different with composers trying to 'write music for the sake of music' and not attaching it to a social meaning or meant for a social cause (see Darmstadt School). The LP City of Glass and the whole body of work from the Stan Kenton orchestra and Robert Graettinger (19471953) is a direct product of the experimental American music scene of the post World War II era. Though overshadowed historically by other compositional endeavours in jazz at the time attributed to George Russell, Neal Hefti or Lennie Tristano, Graettinger and City of Glass is important in the progress that was to be part of Third stream jazz.

PROBLEM: Passage: The path of modern NY85 west of Slingerlands roughly follows that of the Albany, Rensselaerville, and Schoharie Plank Road, a plank road established to connect the city of Albany with the town of Schoharie by way of passing through Rensselaerville. The Albany, Schoharie, and Rensselaerville Plank Road Company was organized on October10, 1849, with Lansing Pruyn as president. On March25, 1850, the company was given a 30-year charter; and the road from Lydius Street in Albany (today Madison Avenue) to the hamlet of New Salemnow New Scotland Avenue in the city of Albany and New Scotland Road in Bethlehem and New Scotlandand the portion of the road from Bernville to Gallupville were planked with wooden boards. Portions of the plank road were already long established roads, such as the Beaverdam (or Beaver Dam) Road in western Albany County near New Salem, which had already existed for quite some time prior to moving to an easier grade around New Salem in 1806. The plank road/turnpike spurred the development of many places along its path, such as a hotel at what would evolve into the hamlet of Hurstville and a post office at what would become the hamlet of Slingerlands.

PROBLEM: Passage: The Yardbirds are an English blues rock band from London. Formed in May 1963, the group originally included lead vocalist Keith Relf, lead guitarist Anthony "Top" Topham, rhythm guitarist Chris Dreja, bassist Paul Samwell-Smith and drummer Jim McCarty. In October, Topham was replaced by Eric Clapton. He remained until 13 March 1965, when he left due to creative disagreements. Clapton recommended Jimmy Page to replace him, but he declined and Jeff Beck took over. Page later joined on bass the following June, after Samwell-Smith abruptly quit; Dreja later took over the role, allowing Page to join Beck on guitar. This lineup was short-lived, however, as Beck left in November 1966. The group continued as a four-piece until July 1968, when Relf and McCarty left due to creative differences, primarily with Page. Dreja initially remained, but by August Page formed a new group with vocalist Robert Plant, bassist John Paul Jones and drummer John Bonham, who later renamed themselves Led Zeppelin.
