The funny thing in this situation is that I'd actually consider Messiaen to be even heavier than Mastodon/Grog Shop -- albeit, less sustained in its heaviness. Mastodon shreds live but all the amps in the world couldn't make them as intimidating as the rhythm section in the Turangalîla-Symphonie. Still, sounds like a good night!
That was actually the 2nd time I'd heard that piece performed live. The first time was in 1989 with Esa-Pekka Salonen conducting the Cleveland.. It was just simply devistating. I practically lept from my seat at the end. Salonen really let the orchestra rip...
When I got back to my dorm, my roomate had just returned from hearing Cecil Taylor peform next door at the Cleveland Institute of Music. Being a huge fan of all things modern and atonal, he was freaking out too. If only I could have caught both shows.. my head probably would have exploded.
I love nights like that..
