The Czech conductor Jiri Belohlavek first recorded a Martinu Symphony over thirty years ago, and has recorded all of them except the Second before these recordings made during the celebrations in 2009/10, in some cases several times. These performances show the results of a lifetime dedication to the composer, and also of his work with the BBC Symphony Orchestra over his years as chief conductor. The recorded sound is fine - these are live performances but there is no sign of audience noise. As a complete set of symphonies it easily takes first place. There are individual performances from earlier periods on CD by conductors such as Ancerl, Munch and Turnovsky which hold their place, and always will, but amongst more recent issues these performances are not only unbeatable as a set but also in the case of the individual symphonies. It is interesting to compare the performances with those by the Czech Philharmonic with the same conductor, and that set, from Supraphon, should soon be complete also. Martinu had himself been a member of the Czech orchestra, who sometimes show particular insight into a phrase or aspect of balance, but the BBC orchestra in these performance on Onyx seem to win on enthusiasm and, surprisingly, in some places also on virtuosity.
