The Blu-ray version of the release 'Tango!' by the Isabelle van Keulen Ensemble features a video of the studio performance of several of the Argentinean composer Astor Piazzolla's most popular pieces, including Verano Porteno, Oblivion, and Libertango. Accompanied by a special documentary, 'Music from the Heart', which presents interviews with ensemble members and behind-the-scenes footage of the studio recording process. The Isabelle van Keulen Ensemble was formed in January 2011 by the critically acclaimed Dutch violinist and violist Isabelle van Keulen especially for a series of concerts in Haarlem's Concertgebouw which showcased the music of Ástor Piazzolla.
The Vienna Art Orchestra is a 15-member jazz orchestra that features the avant-garde arrangements and compositions of its leader, pianist Mathias Ruegg. This is a reissue of their 1980 debut, an important document in the post-modern jazz movement. The opening, title track is a joyous, folkish tango that's been cartoonishly toyed with, featuring three solo sections. The marimba section is also ornamented with vocalese from Lauren Newton, followed by an extremely playful horn lead that sounds like a toy instrument. The solo offering from violinist Rudi Berger has an electronically effected fusion sound. A tight, alto sax solo by Wolfgang Puschnig ties everything together neatly with a lengthy, unaccompanied performance.
