My favorite album all time. Love every damn second of disc 1 and disc 2. Glass Prison got me into DT and even if it took a while to fully appreciate the album it grew over time and finally became the one.
It always stands the test of time for me. Listened to it so many times and I never get bored of any song or moment.
Words that come to mind; creative, progressive, experimental, joy, symphonic, energy, melodic, diverse.
