I love the music of Philip Glass. I completely fell in love with Solo Piano. For this one though, my favourite tracks are Facades and Closing, with Closing being the best track, in my opinion.
The others are a little too discordant for my tastes although, in fairness, Philip Glass does like to play with the discordant in his compositions. Therefore I found Opening not enjoyable and Floe and Island difficult in places. An acquired taste I think but not for me.
