Neeme Järvi’s last season with the Detroit Symphony Orchestra is unveiled, and it plays like nothing so much as a summing up of the 15 years of artistic growth which the Motor City has enjoyed under the Estonian maestro. There are crowd-pleasers (Carl Orff’s Carmina Burana,) and critic-pleasers (Ned Rorem’s Third Symphony,) but mostly, there is the enthusiastic personality of Järvi himself, capped off in the final three weeks of the 2004-05 season, when Järvi the father will be joined, on stage, by his three children: flautist Maarika, and conductors Paavo (of the Cincinnati Symphony,) and Kristjan.
