The classical symphony is so dominated by the twin figures of Haydn & Mozart that it is all too easy to overlook the considerable contributions which were made by many lesser figures. The Naxos label is doing a great service by bringing to light many of these works in its '18th Century Symphony' series. It now launches a survey of the symphonies of the Bohemian composer Johann Baptist Vanhal with four highly spirited, engaging pieces dating from 1760-1780 that are the equal of Haydn's contemporary efforts. These are witty, original pieces and it's easy to see why Imperial Vienna took them immediately to its heart. Uwe Grodd and the very fine Hungarian players of the Nicolaus Esterhazy Sinfonia make a strong case for them.
