The English Baroque Soloists is a chamber orchestra playing on period instruments, formed in 1978 by English conductor Sir John Eliot Gardiner. Its repertoire comprises music from the early Baroque period to the Classical period. For Philips it has recorded all of the mature symphonies (as well as the Requiem and Mass in C minor) and for DG Archiv it has recorded the complete piano concerto cycle with Malcolm Bilson, the first on period instruments.
