I would have to agree with the first reviewer that McCreesh's Saul has to be the definitive recording, if anything can be said to be definitive. The characterisations in oratorio can be difficult to pull off, particularly if there is not a lot of recitative; everything therefore has to be put into the arias, many of which are not da capo, and offer limited scope for interpretation (only in comparison to his operas of course)
For me, the highlight of the 3 competitively-priced discs has to be the scene where Saul confronts the Witch of Endor, and then Samuel the prophet is brought forward. The scene is spine-tingling and utterly believable. Of course, the lovely singing of Andreas Scholl is a contributing factor to giving this recording 5*, but to pick him out when there is so much good singing evident would to be invidious.
Previous recordings by John Eliot Gardiner (Philips) with Derek Lee Ragin as David, by Charles Mackerras (DG Archiv) which is no longer available and which had James Bowman as David, or Budday's recent recording with Michael Chance as David, all have something special about them. However, each of these recordings had flaws (live,incomplete etc), whereas McCreesh's just seems 'right'.
Even if you are not a baroque buff, this Saul should whet your appetite to explore the work of a great dramatic genius in Handel; if you like good singing, there is enough to sate the most hungry of listeners. I would give it more than 5* if possible !
