The largest brass band consisted of 15,761 musicians who gathered to play during mass at an event organised by the Evangelische Posaunendienst in Deutschland e.V. at the WM Stadium, in Leipzig, Germany, on 1 June 2008.

The conductor was in the middle of the field and the musicians followed him through a giant screen. Due to the vastness of the stadium, there was a 2 second delay between conductor and music.
