Mr. B. J. Lang, the almost lifelong organist and steadfast helper of the Handel and Haydn Society, and for a time the successor of Carl Zerrahn as conductor, has shown in countless ways such consummate skill, tact, and artistic judgment that he has won the admiration of all musicians. […]  While still very young he organized, in 1862, a couple of concerts, in which he appeared as the conductor of a large orchestra, chorus, and soloists, in two performances of the Walpurgis Nacht. He thus entered upon a broad, artistic life, and has continued in the same path. He has been the conductor of the Apollo Club since its formation in 1871, and also of the St. Cecilia Club. The first concert of the latter was given November 19, 1874, orchestra assisting. The programme consisted of several part-songs and the Walpurgis Nacht, by Mendelssohn.
