The 21st is an excellent introduction. You could consider the 6th, which is, with or without choral end, a stunner. Take Jarvi with the Gothenburg forces. The 27th needs attention too. The 17th is worth your time: composed at the height of the Great Terror, its idiom seems a little more extroverted than usual, Rachmaninov crossed with Khachaturian perhaps. The epic slow movement will be a must for listeners with a sweet tooth! No 22, called a 'symphonic ballad' is my favourite. Try Svetlanov's readings.
Thank you kindly. That seems like enough to get me started. I do have a sweet tooth!
