Volume Five pairs two relatively early works of Lutoslawski with two works of his full maturity. The 'Concerto for Orchestra' of 1955 is a brilliant example of Lutoslawski's orchestral craftsmanship. It also demonstrates that he was a great composer well before he explored the more personal idiom of his later music. Also from this period is the tiny Overture for Strings of 1949. It is a lovely work that has been completely overshadowed by the composer's first symphony as well as the more famous 'Funeral Music.'
From the composer's full maturity comes his only work for chorus and orchestra, the 'Three Poems of Henri Michaux.' The score specifies that the two ensembles are only loosely coordinated, and each has its own conductor. The middle movement is a brilliant evocation of a crowd on the verge of riot. Finally there is 'Mi-Parti,' from 1976, a two-part single-movement work written for the Concertgebouw Orchestra of Amsterdam. As always in this series, the performances are completely competitive and offer much repertoire not available elsewhere--and all at a budget price.

Somewhat unusually, the fourth volume of the Naxos series of Lutoslawski orchestral recordings concentrates entirely on the music of his full maturity where the composer used brief passages of aleatoric counterpoint. As the composer stated many times, this is not improvisation: All the music is written out, but the precise coordination over a set duration is left to the moment. Thus each performance is, in its small details, literally unique. By the time of 'Livre pour orchestre,' written in 1968, Lutoslawski had begun to incorporate a certain amount of indeterminacy in all of his music.
The masterful Cello Concerto, written for Rostropovich in 1970, marked Lutoslawski's mature return to concertante writing. At the great cellist's request, only musical considerations were taken into account, hence the fearsome solo part. It is one of the composer's finest works, and is very well performed here. The 'Novelette' was also written for Rostropovich, this time as conductor, as a companion piece to the Cello Concerto in 1979. Finally, from Lutoslawski's last period comes 'Chain No.3,' the last of three works all employing a similar chain method of construction. All three works reflect the increasingly refined idiom of Lutoslawski's final decades.
