Rondo of the Waves' is the title of the fifty-first volume of the BIS Sibelius recorded edition. This is a particularly engaging disc because of its brim full of splendid music while simultaneoulsy presenting a succession of previously unheard scores that will be of particular interest to anyone who enjoys the music of the great Finnish composer. The 'Waves' of the title are those of Sibelius' famous tone poem 'The Oceantides', described by one famous critic as the 'finest evocation of the sea which has ever been produced in music'. The tone poem that we know today had a long period of gestation, starting life as part of an orchestral suite and then undergoing two complete metamorphoses before evolving into the masterpiece that we know. Clearly Sibelius was fascinated with his original material and, in two preliminary versions of the tone poem he conducted some very striking experiments with it, producing music that is more extravagantly impressionistic and kaleidoscopic than anthing else he wrote. These important scores have lain forgotten since they were first produced and were performed for the first time in the autumn of last year by the Lahti Symphony Orchestra conducted by Osmo Vänskä. Subsequent to their first public airing they were recorded by the same forces and are now available on disc for the first time - together with another 40 minutes worth of previously unrecorded orchestral scores by the master's hand. As well as the original materials, the disc also contains a fine performance of the final version of 'The Oceantides', lifted from last year's highly acclaimed 'Sibelius Tone Poems' (BIS CD1225)
