Often bracketed with Bach, Handel and Bach were as different as contemporaries could possibly be. I would instead compare Handel with Schubert, history's worldliest and un-worldliest composers, but both with an infinite gift for melody, one lovely, ravishing melody after another, and another. But Schubert can be depressive, Handel never - being acclaimed and rich, it may be, is better than being little appreciated and poorer than a church mouse; being large and imposing is also better than being so small and round as to be nicknamed Mushroom.
As for Bostridge, there are many ways to perform Handel. Bostridge's is the gentle way, emphasizing melody over rhythm, sweetness over strength; it works for me, though I like the other ways too. Sung as Bostridge sings it, this is the most heart-stabbing, almost heart-breaking music ever composed, and yet also the most peaceful, serene. If you take an ace inhibitor or calcium channel blocker, try this instead to lower your blood pressure and slow your pulse with no side effects whatsoever; and, into the bargain, an antidote to the cynicism generated by events in the quotidian world of politics, economics, and unending war - not to worry, God won't end the world while such music exists.
