It has been musically treated by Handel and Mendelssohn.
But in music he had no more to learn, and Parsifal, while the most solemn and concentrated of all Wagner's dramas, is musically not always unsuggestive of old age.
Seriously, tho, whilst this is all musically accomplished, lyrically it's all a bit too for me testosterone-fuelled.
Musically the band were excellent, although if you expect mostly acoustic think again.
No audition required Guildford Sinfonia is an orchestra for musically adventurous adults.
