Some of my favorite Shostakovich Wanna bees.

Revol (not to be confused with Vladimir) Bunin or Bounine (his 5th
Symphony is a favorite)
Galynin-a delightful Piano Concerto
Gordelli
Kara Karaev
Ovchinnikov (First Symphony and Symphony for Strings)
Rakov
early Shchedrin
Shebalin
Taktakishvilli
etc.

Not to short change these composers, but I do hear some influence.

Coincidentally, yesterday I was doing some restoration work on a the
Morton Gould First Symphony. At more than one point, he quotes the
Shostakovich First Symphony!
