Another great work of Suk is "The Ripening", which might be called Ein Heldenleben for introverts. The work is intended to portray the process of maturing as a person,going through the various trials and tribulations of life.
I found that this took a number of hearings to grasp, but I'm glad I made the effort.
I have the superb Supraphon recording with the great Vaclav Talich and the Czech Philharmonic, in dated but listenable sound, coupled with the engaging suite from Raduz and Mahulena, the music to the play.
I've also heard the more recent version with Libor Pesek and Liverpool,
also excellent, in up to date sound,coupled with Praga.
I would recommend either,but if you want much better sound, go with Pesek.
