To commemorate the 150th anniversary of the death of Anton Diabelli we are publishing the two additional movements of his first "Country Mass", the remainder of which is already available. These two movements, suitable for use during any period of the Church year, are further cause to perform at church services and in concerts the Mass in E flat major, which despite its simplicity can be impressive in effect. The flexibility in the size of the orchestra intended by the composer makes this work ideal for churches whatever their instrumental resources are. Solo B, Coro SATB,[Fl, Clt], 2 Cor,2 Vl, [Va], Bc
