The English Chamber Orchestra (ECO) is a British chamber orchestra based in London. The full orchestra regularly plays concerts at Cadogan Hall, and the ECO Ensemble performs at Wigmore Hall. The orchestra regularly tours in the UK and internationally, and holds the distinction of not only having the most extensive discography of any chamber orchestra, but also of being the most well-travelled orchestra in the world; no other orchestra has played concerts in as many different countries as the ECO.[1]
