As an organist, chorister, choral director, composer etc, etc... I have heard and sung Messiah more times than I care to remember (and I am just 17!) My parents raised me on a healthy diet of Handel and Bach, and so over the years I have come to know and love many works by these great masters, and indeed performing a great deal in more recent years. I have heard many, many recordings of Messiah and, to put it simply, this recordings beats them all into submission. From the moment of the first few chords in the overture to the last bars of the final chorus, this is a true masterpiece of baroque performance from every angle - and I do not say that lightly. The fact that I have now started listening to Messiah for pleasure, rather than for duty or necessity, speaks for itself.
In response to Mrs Barrowman's review below, I would question all the points she has raised. Firstly, whether one is a "baroque purist" or not, this is a hugely enjoyable disc filled to the brim with technical perfection and precision. She refers to the "white sound" of the trebles - I can only think she means "pure" sound - not pure in the sense of some 1980s recordings of King's College Cambridge, which on occasions verge on being quite dry, but truly clear-cut and precise.
Furthermore, I would dispute the so-called "richness" of the female voice in other recordings. Take the venerable Helen Watts in the aria "But who may abide the day of his coming?" (an aria Helen sings superbly), and compare it to the rich clarity of Iestyn Davies in this recording, and there is no competition whatsoever (and let us not forget this is an English oratorio, not an Italian Opera, even if the composer was fluent in both styles!) This recording succeeds in re-addressing the work in its proper light, and not in the hideous tradition of romping through the repertoire that has found its way into British musical culture (is it any wonder so many choirs and conductors are board to tears with it?!) One huge attraction for me was the performers' approach - simple, humble piety as opposed to the pretentious showmanship we normally experience in the concert hall - this recording is just so fresh and invigorating!
Apart from being more authentic (ah those purists again!), the sound produced allows for a crystal-clear annunciation of every syllable, every quaver, every ornament; whereas dear Helen & Co might as well be singing in Japanese. Overall, the soloists in this recording are truly outstanding, the counter-tenor in particular. Other soloists include three trebles from the choir (all of whom are rather good), and wonderful performances from the tenor, Toby Spence (a name many will be familiar with), and the bass, Eamonn Dougan.
One thing is for certain: this recording is different and definitely fills a gap in the market. Those who have heard or sung Messiah so many times they are bored to tears with it, they should buy this recording - this rendition is so fresh, so invigorating that it is like listening to a completely new work. The edition selected is the 1751 version (use by the composer for performances in London), which provides a very pleasant change without resorting to the dreaded blasphemy of Mozart's arrangement of the work. And so what if we're used to wobbly female voices? Alcoholics are used to drink, but it doesn't make it right, nor any good for their health.
Out of the many recordings I have heard, this is certainly the most technically assured, the most accurate and authentic (both musically and historically), and, more importantly, the most enjoyable.
