Elisabeth Lutyens

[Uhor]

Agnes Elisabeth Lutyens, CBE (9 July 1906 – 14 April 1983) was an English composer.

She composed a number of works for various forces mainly in a personal realisation of the 12 tone technique with a result similar to Webern's. 

Sadly she is somewhat poorly recorded outside of her piano works.

Some examples:

I have a few pieces by Lutyens -

And Suddenly it's Evening (Instrumental ensemble)
Quincunx, after Sir Thomas Browne - orchestral songs
String Quartet No 6
Six bagatelles
O saisons, o chateaux - cantata

She also wrote a fair amount of film music - mainly for Hammer Films - to support herself, her children and her feckless husband
