This 53-CD set is more than the sum of its parts. While not all the performances and recordings are top-notch, the overall quality is very high and as a historical overview of a label known for its sonic as well as musical merits, it's full of treasures. The Mercury sound at its best is vivid and still sounds remarkable and many of these recordings - such as the marches, show tunes and orchestral showpieces conducted by Frederic Fennell - demonstrate this amply. But it's not all lollipops by any means.
The London symphonies, sometimes called the Salomon symphonies after the man who introduced London to Joseph Haydn, were composed by Joseph Haydn between 1791 and 1795. They can be categorized into two groups: Symphonies Nos. 93–98, which were composed during Haydn's first visit to London, and Symphonies Nos. 99–104, composed in Vienna and London for Haydn's second visit.
Every London Symphony, apart from one (No. 95), has a slow introduction to the first movement.
