So, last night I saw the smashing pumpkins play in the progress energy center in raleigh. Review to come, great show (no pics unfortunately, except of a filling venue).
Now, I'm not sure if they actually did this in their show, or if its an idea that came to me watching them. The final song of the show, before the encore, was a 30 minute or so psychedelic freakout thing, but I swear they were tuning their guitars in the middle of it. So the idea is (they didn't do this specifically, as after the encore were two singalong kind of songs, one being "we only come out at night", the other I'll leave as a surprise for the review ), during the middle of a song you have a rather short, at least compared to a thirty minute experiment, part where you mess with all of your effects, have fun, a good time to mess with your delay's feedback or delay time knobs, and your favorite 'make-a-mess-out-of-your-tone' effects, but all the while detuning your guitar.
At first you can incorporate it into the song, say rhythmically just detune all of your strings (much like paul gilbert does at the end of this song), doesn't have to be a specific amount, just drop them a few tones, mess with some effects, maybe solo a little bit. Have some heavy delay feedback or something similar to give the audience some noise while you then tune your strings up, but to a dropped (or open or whatever really, just a different tuning in the same song) tuning for say, some really heavy riffing to end the song. Or you could do it again to go back to the normal tuning again after a while.
Just an idea I had at the show last night. What do you think?
