The Philharmonics, the ensemble founded by members of the Vienna Philharmonic Orchestra, fill the Café Sperl with some of the most authentically Viennese sounds imaginable  the Strauss waltzes that Schoenberg, Berg and Webern arranged and performed in May 1921 to raise funds for their pioneering Society for Private Musical Performances. This is music the players have in their blood, and they maintain the echtatmosphere with Godowskys tribute to the city, Alt-Wien and a clutch of Kreisler gems, rounding the programme off with a new piece by the ensembles leader Tibor Ková, based on traditional Jewish melodies and Mahler themes, Yiddische Mame.
