Rushton has given you some good composers to ponder. Along those lines you might also like Edward Elgar, particularly his less well known works like Starlight Express. He directly precedes RVW in British musical history. Also try William Walton, particularly his Cello Concerto. Walton is a musical decendent of RVW and gives you a glimpse of British music just following RVW.
