Fascinating thread - but not necessarily good for my bank balance

Here are some recommendations from me:
Allan Petterson Symphony 6-8
Rootham Symphony 1 (Lyrita)
Stanley Bate (Symphony 3 and 4, Dutton) No 3 is wonderful, powerful, tonal, moving, defiant at the end - and Bate had a difficult life.
Klaus Egge: Symphony No 1 (might appeal to fans of Walton Symphony No 1)
Joubert Symphony 1 with Mathias Symphony 1 (Lyrita) - both excellent - lyrical, powerful, tonal, moving.
Hoddinott Symphony No 3 - not easy but has a gritty integrity and is ultimately rewarding
Braga Santos symphonies 3 and 4 (great composer - might appeal to Sibelius/Vaughan Williams fans.
Tubin - all symphonies
Holmboe symphonies 4,6,7,8,10
Miaskovsky (my favourite) symphonies 3,6,15-17,21,24,25,27
Weinberg nos 1,3,5 and 6
Arnell nos 3,4,5,6
Alwyn (all symphonies)
George Lloyd nos 4,7,8
Bantock, Hebriddean, Celtic, No 3
Arnold No 1,3,5,6,7,9
Lilburn symphonies 1 and 2
Wiren nos 3 and 4 (great!)
Ivanovs Nos 2,3,4,8,20 (last two on Naxos)
Popov Nos 1and 2
Eshpai Nos 4 and 5
David Diamond No 3 (v moving)
William Schuman (no 6)
