Henry Purcell, ‘Symphony while the swans come forward’,

…Interesting to notice that Fentross may have learned a lot from Ton Koopman, but in the meanwhile he searched for his own sound and found it. Noticable about his sound is the ‘souplesse”, the transparency and the space in the dynamics. In particular the stringorchestra is fascinating us with breathtaking pianissimi Opusklassiek September 2018

La Sfera seems to have resurected Purcell in truest form NRC May 2018

La Sfera Armoniosa, founded in 1992, is a Dutch Baroque ensemble and orchestra specialized in the performance of music from the seventeenth and eighteenth century. Artistic director and conductor is Mike Fentross. In addition to the music of famous composers such as Monteverdi, Haendel and Vivaldi, the ensemble undertakes research into the manuscripts and printed works of the European libraries in order to provide a rich spectrum of music from lesser known composers. The English music magazine Gramophone wrote about their first cd: “How soon will we hear the enchanting La Sfera Armoniosa again, and what fresh buried treasure will they unearth?” La Sfera Armoniosa is known and praised for it’s lively and colourful sound and for its groundbreaking programmes. They created in 2004 a Schoenberg/ Monteverdi programme that they performed with great success in the Utrecht Early Music Festival and they performed modern world premiers from three almost forgotten opera’s: La Rosinda, l’Ipermestra and Granida. In 2012 the Concertgebouw asked La Sfera to design and perform a special program, the Amsterdam musical life before the concerthall was build, for their 125th anniversary.
La Sfera Armoniosa performed in main festivals and concert halls such as: Festival van Vlaanderen, Festival d’Ambronay, Festival Oude Muziek Utrecht, Music Center Vredenburg, Musikfestspiele Potsdam Sanssouci, Monteverdi festival Cremona, Festival de Musica Portico de Zamora, Festival Musica Antiqua Bruges, and the Concertgebouw of Amsterdam.
About their performance of the opera La Rosinda by Francesco Cavalli in Musikfestspiele Potsdam Sanssouci the press wrote: "This evening, the orchestra has proven that it is amongst the leading baroque orchestras. I will not soon forget the nuances that came from the orchestra pit. That was great art. Nothing more and nothing less."
