Joachim's time in Hanover was his most prolific period of composition. Then and during the rest of his career, he frequently performed with Clara Schumann. For example, in October–November 1857 they took a recital tour together to Dresden, Leipzig, and Munich. St. James's Hall, London, which opened in 1858, hosted a series of "Popular Concerts" of chamber music, of which programmes from 1867 through 1904 are preserved. Joachim appears a great many times. He visited London each year from 1866 on. In March 1898 and in 1901–1904 Joachim appeared in his own quartet of players, but otherwise far more often he appeared with resident Popular Concerts artists Louis Ries, second violin, J. B. Zerbini, first viola, and Alfredo Piatti, first cello, reputed to be "one of the most celebrated cellists" of the time. George Bernard Shaw wrote that the Popular Concerts had helped greatly to spread and enlighten musical taste in England. Joachim had been a mainstay of the chamber music Popular Concerts.
