L. Kozeluh / F.J. Fröhlich
CD 3-6504-2 H1

Concerto:
"The concerto by Fröhlich is a real discovery: a highly original work. The two (pianists) achieve their task in exemplary ensemble and virtuoso coordination. This CD rescues two valuable works from oblivion and presents them faithfully. To be recommended!"

Piano News:
"The Kölner Klavier-Duo responds to the demands of the music agilely and nimbly without neglecting for one second the "single breath" for the form as a whole.
... the two (pianists) are so attuned to each other, they produce a homogeneous sound which is bewitchingly precise."

Neues vom Phonomarkt, NDR 3:
"Unusually balanced, the pianists Elzbieta Kalvelage and Michael Krücker. The Duo fascinates the listener because they have the same dynamic energy in their touch and they play, as it were, in one breath, with the same phrasing, so much so that the ear cannot tell them apart."

"It is very gratifying when a capable piano duo, which plays together as one, succeeds in offering a CD whose repertory is unconventional and rewardingly informative.
Two conservative minuets, a festive march in the style of Franz Liszt and a lively polonaise complement this attractive programme, and it will no doubt appeal widely, not only to specialists."

Die Zeit:
"... is the proof that the arrangements can surpass the original, with the Kölner Klavier-Duo at any rate. The basses reverberate, the chords pulsate, the tempo presses ahead briskly…"

Luister:
"... outstanding Duo... ... extraordinary programme. The performance of this overwhelming programme is a tremendous celebration from beginning to end... ... infectious musicality... ... sparkling... ... romantic without being heavy, as elegant as Mozart."

Klassik.com:
"… at the highest artistic level… ... impressive… ... play together in absolute oneness…
The emotionality is expressed with sensitivity, and the liveliness of the interpretation is a delight to listen to. ... played with musical bravura, the dynamic presentation is combined with fine differences of touch in a wealth of nuances. The homogeneousness and precisely attuned coordination are impressive and characteristic of the outstanding musical and technical stature…"
