Another series of concerts related to the Classical Concert Society - the same artists played in both series - was the Northlands Chamber Music Concerts, held at Englefield Green. These concerts, arranged by Tovey, had begun in 1893, but Bridge's name as a performer did not feature in the programmes until 1906. Naturally enough, Tovey's works were performed quite frequently; Bridge's were heard not at all.
Although Bridge had officially left the College, 'his viola playing was so much in demand in chamber music that he seemed to be constantly in College, just as Ivor James and Harold Samuel were'.4 In fact, Bridge played in most of the student chamber music concerts until the summer of 1910. During 1905, for instance, he was required for twelve concerts and, bearing in mind his additional visits to the College to attend rehearsals, his face soon became familiar to the next generation of students, which included Beatrice Harrison, William Murdoch and Felix Salmond. One of the College concerts was particularly notable. On 19 October 1904, Bridge, with Vera Warwick-Evans, Herbert Kinsey and Ivor James, played Debussy's String Quartet, one of the earliest performances of the work in England. Parry, who was in the audience, was much taken with the quartet (but not the performance) and hoped that it would be repeated at another concert in the near future.5
Bridge was also active in the Royal College of Music Union.6 At regular intervals there would be musical evenings at members' houses, and the English String Quartet or, as it was called in the earlier concerts, the College Quartet, would be invited to play. At least one work by a College composer featured in each programme, and Bridge's Piano Quintet (1904/5 version) was performed at one of these concerts for the first time (28 May 1907). Ethel took the place of Herbert Kinsey in the quartet; the pianist was Harold Samuel. By coincidence, the first performance of the revised version of the quintet (1912) also took place at one of these concerts, on 29 May 1912.
