Biber's Missa Salisburgensis is one of my favorite Baroque choral works!! It tricky to record well though, since is requires such a gigantic space with two orchestras & so many singers. Unfortunately, I've never heard it live, but on recordings there is a tendency for the ensembles to all sound a bit too distant or engulfed within a huge space.
My two favorite recordings are by (1) Musica Antiqua Köln and the Gabrieli Consort & Players, led by Reinhard Goebel (who's a very seasoned Biber conductor & violin player) & Paul McCreesh, respectively, and (2) Jordi Savall with Le Concert des Nations and La Capella a Reial de Catalunya. (By the way, Savall has made two other excellent Biber choral recordings.) The McCreesh/Goebel recording was initially issued on hybrid SACD, but I don't know if the hybrid SACD is still obtainable. As you might imagine, it was a particular treat to hear this music on a hybrid SACD (& even on a conventional player it sounded great, as I used to play the disc often in my car).

Ton Koopman has also recorded the Missa Salisburgensis with the Amsterdam Baroque Soloists on Virgin Veritas/now Erato, but I've not heard that recording. It's on You Tube though, if anyone's interested:
. The Luks recording has been commercially released as well. EDIT: Oh yes, there's also a recording on a NCA hybrid SACD by La Stagione Armonica & Tibicines, led by Sergio Balestracci, which I've heard is very good, but I haven't heard it myself:

Since all of these recordings are by period instrument ensembles & conductors, including the Luks DVD, & I don't know of a single recording that was ever made on modern instruments, it has me wondering if this is yet another extraordinary piece of music that the period revival has rescued from obscurity and brought back to life for us? If so, I am very grateful.
Here are links to the other two Savall Biber recordings, which are very recommendable, as well--especially if you are looking to explore Biber's choral output further:
