In nearly every respect this is outstanding. The Rondo brillant and the Fantasie, both written for the virtuoso duo of Karl von Bocklet and Josef Slawik, can sound as if Schubert were striving for a brilliant, flashy style, foreign to his nature. Both are in places uncomfortable to play (when first published, the Fantasie’s violin part was simplified), but you would never guess this from Faust’s and Melnikov’s performance; they both nonchalantly toss off any problem passages as though child’s play. The Fantasie’s finale and the Rondo brillant are irresistibly lively and spirited, and this duo’s technical finesse extends to more poetic episodes – Melnikov’s tremolo at the start of the Fantasie shimmers delicately, while the filigree passagework in the last of the variations that form the Fantasie’s centrepiece have a delightful poise and sense of ease.
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.
