For 10 points, name this composer of Symphonic Dances and Rhapsody on a Theme of Paganini.
Alexander Warenberg arranged one of this composer's symphonies into a concertante work for piano and orchestra he dubbed this composer's fifth piano concerto. The scherzo [SCARE-tzo] of that symphony by this composer ends with full brass playing a modification of the Dies Irae melody, which is introduced by chimes in the final movement of another of his pieces. That latter piece by this composer has a folk-like saxophone solo in its "Non Allegro" first movement and quotes a theme from his first symphony, whose (*) premiere was screwed up by a possibly-drunk Alexander Glazunov. The hypnotist Nikolai Dahl helped this composer recover from that failure and received the dedication of this man's second piano concerto, which opens with bell-like chords.
