The Battalia à 10 is played with great style and charm here. I like the use of two theorbos and a harpsichord and organ on the continuo lines. I have several recordings of this work. Savall's approach is a little more polite than Goebel's and a little more atmospheric than Philip Pickett's quite raw sound. I like all of them. Savall's is, perhaps, the most beautiful recording, even though it doesn't take advantage of the musical effects Biber suggests with as much relish as Goebel or Pickett.
The A Major Requiem à 15 in Concerto is a favourite of mine and the only other recording I've ever heard is Ton Koopman's with his Amsterdam Baroque Orchestra & Choir on ERATO. I've loved Koopman's recording ever since I bought it, shortly after it was released in the 1990s. It was coupled with the magnificent Vesperæ à 32 voci. I was eager to hear another recording of this little known work. Only two requiems by Biber have survived, this one, in A major and the F minor Requiem. Both are masterpieces and each takes a different approach. The A Major work features trumpets, trombones, timpani, oboes (perhaps added later?), dulcian [fagotto], strings and, of course, basso continuo. The F minor work uses strings, two dulcians, three trombones, and multiple organs and is a much more sombre and darker work.
Savall's recording was made in Salzburg Cathedral and takes advantage of four of the organs in there. The sound is beautiful and splendid and, indeed, moving. We are transported to a beautiful world without pain - a glimpse of Heaven, in fact. The opening Marcia Funebre gives one the opportunity to wind and brass of Le Concert des Nations in the Salsburg Cathedral space. What a sound! It is worth buying the disc for the March alone. The Requiem in Concerto which follows is a beautiful and radiant work - full of hope for the afterlife and great grace and beauty.
I hope Jordi Savall and his ensembles, La Capella Reial de Catalunya and Le Concert des Nations, get around to recording the deep, dark and sober Requiem in F minor some time soon.
This current disc is highly recommended by me.
