In March 1823, Moscheles paid a long visit to Bath in Somerset and started work on his Piano Concerto No. 4 (Op. 64). On an excursion to Bristol, Coleridge says that, "Moscheles delights in the view of the Bristol Channel and adds, "What can be finer than the first view of the Welsh mountains from Clifton? an enchanting panorama? The very place to write an adagio; the blue mountains form such a grand background to this bright channel." The piano concerto had its first performance, in London, shortly afterwards, on 16 June.
