A documentary film by Bruno Monsaingeon devoted to the 20th century's greatest violinists, The Art of Violin really cannot be faulted. The same, incidentally, can also be said of the similar volumes that cover the piano and singing, so there's never been a better time to collect a personal audio-visual archive of some wonderful historical performers. The added dimension provided by the painstakingly collected film material (here featuring no fewer than 20 outstanding soloists) is of exceptional value when observing violin technique, and the diversity of approaches presented here in loving detail is in itself a subject for endless comparison. The material mixes archive performance footage, much of which one might never have dreamed existed, with interviews and documentary commentary. However, rather than turn the project into a museum piece, Monsaingeon includes contributions from contemporary figures such as Itzhak Perlman and Hilary Hahn. An absolute must.
