Question: What year was the man whose music inspired Folias Flute and Guitar Duo born?
Context: Music Inspired by Watership Down is a progressive rock album by Swedish musician Bo Hansson.  The album is Hansson's fourth solo album and is, as its name suggests, built around musical ideas inspired by Richard Adams' heroic fantasy novel "Watership Down".  It was the second album of Hansson's to have been based on a novel; his first solo album, "Music Inspired by Lord of the Rings", had likewise been based on J. R. R. Tolkien's "The Lord of the Rings".  Hansson had already composed and released a musical suite inspired by "Watership Down" on his previous album "Attic Thoughts".  However, beyond its title, the "Music Inspired by Watership Down" album contains few overt references to the novel and instead features excerpts from the works of various poets, such as John Keats and Alexander Pope. The Send was an alternative rock project of Falling Up ex-guitarist, Joseph A. Kisselburgh of Albany, Oregon, currently signed to Tooth & Nail Records.  His debut album, "Cosmos", was released on July 31, 2007.  Before this was even released, though, his song, "The Fall", was featured on "Charlotte's Web: Music Inspired By The Motion Picture", a compilation album with music inspired by the 2006 movie of Charlotte's Web.  On June 23 The Send began a winter retreat with labelmate, Hawk Nelson, around Major League Baseball venues.  The first single off "Cosmos" was "An Epiphany," which quickly gained some success, reaching No. 5 on Christian Hit Radio. Gertrude Abercrombie (February 17, 1909 – July 3, 1977) was an American painter based in Chicago.

Astor Pantaleón Piazzolla (] , ] ; March 11, 1921July 4, 1992) was an Argentine tango composer, bandoneon player, and arranger.

A virtuoso bandoneonist, he regularly performed his own compositions with a variety of ensembles. Masiakasaurus is a genus of small predatory theropod dinosaurs from the Late Cretaceous of Madagascar.  In Malagasy, "masiaka" means "vicious"; thus, the genus name means "vicious lizard".  The type species, Masiakasaurus knopfleri, was named after the musician Mark Knopfler, whose music inspired the expedition crew.  It was named in 2001 by Scott D. Sampson, Matthew Carrano, and Catherine A. Forster.  Unlike most theropods, the front teeth of "M. knopfleri" projected forward instead of straight down.  This unique dentition suggests that they had a specialized diet, perhaps including fish and other small prey.  Other bones of the skeleton indicate that "Masiakasaurus" were bipedal, with much shorter forelimbs than hindlimbs.  "M. knopfleri" reached an estimated adult body length of around 2 m .

Tango is a style of music in  or  time that originated among European immigrant populations of Argentina (collectively, the "Rioplatenses").  It is traditionally played on a solo guitar, guitar duo, or an ensemble, known as the "orquesta típica", which includes at least two violins, flute, piano, double bass, and at least two bandoneóns.
