The Swedish clarinettist Martin Fröst plays with admirable virtuosity and smoothness of tone, and it’s hard to imagine the music better performed.

Martin Fröst's style of playing is well suited to Weber: he has a clear, fresh tone and fingers undefeated by even the most sensational of the applause music that ends some of these works.
He is not afraid of considerable tempo variations within a movement, as Weber is on record as having wanted.
This all contributes to a charming, eloquent performance of the Concertino. However, the F minor Concerto (No 1) does not need its opening Allegro to be taken quite so fast for it to make its points, and the finale, here sounding like a brisk allegro verging on presto, is actually marked Allegretto, which gives the music more space and freedom. The slow movements of both concertos are played simply, without affectation, and Fröst remembers that the alla polacca of the finale of No 2 is a dance. He takes a bright lead in the Quintet; it is played here as a concerto with full strings, which is a pity but, given the quatuor concertant nature of the work, not as disastrous as it would be with Mozart. This is a fresh, amiable performance that responds to the music's varied nature.
Fröst also plays some cadenzas of his own, rejecting those which were later added by Carl Baermann, son of the much-admired dedicatee of the works, Heinrich Baermann. He further adds a few flourishes: unnecessarily, but there is no need to be too purist here. These are attractive, exhilarating performances, clearly recorded so as to do justice to the orchestral effects which were always part of Weber's exuberant invention.

Fröst just may be the finest clarinetist (sic) alive, and this entire production is typical of what we have come to expect from BIS…There is no more exciting label around today
