Thanks all,
Marek, About reason of composer discarded his earlier symphonies.
Composer said, he found new composing method after he lost his hearing.
He is not able to listen all sound , so he necessarily explore sound in his heart.
At that time, he realized that this is " true sound " for him.
And he felt his earlier symphonies are sounding ' Fake '.
Therefore he discarded these.
His symphony no.2 is ' New work '.
Of course , I interested in his earlier symphonies...
But I'm looking forward to listen his new symphonies
