The All-Night Vigil (Vespers) Op. 37 is an a cappella choral work first performed in 1915. It's fifteen movements consist of Russian Orthodox Church texts. Rachmaninoff had stopped attending church, but he felt compelled to write some of his own chants in the style of the Church, calling them "conscious counterfeits".

The work is enormous, of over one hour of the most beautiful choral writing with Rachmaninoff's patented rich harmonies, melody and polyphony.

Paul Erion has arranged this work for moderately advanced 10-part Brass Ensemble of: 4 Trumpets in C, 2 Horns, 3 Trombones & Tuba.

This bundle of brass ensemble music represents a huge saving on the prices of the individual arrangements, and comprises 5 popular pieces which are ideal for concert purposes. From the quiet, emotional 'Londonderry Air', which has been arranged as per the version featured in the 'Brassed Off' film, to the huge 'Sinfonietta' by Janáand#269;ek, there is a whole range of music here. Much of it is aimed at advanced players as the level of challenge is high, but they all work incredibly well once rehearsed properly. Three of the arrangements also have parts for percussion included with them as well.

Scores and parts are included for:

* The Great Gate of Kiev (Mussorgsky)
* Promenade (Mussorgsky)
* Londonderry Air (Trad.)
* Chorale Theme from ?Organ Symphony? (Saint-Saëns)
* Sinfonietta (Allegretto - Fanfare) (Leo? Janáand#269;ek)
