Honestly, I have had the same reaction. Granted, there are artists who pull it off with panache and a sense of spontaneity's (I think , specifically, of Zoe Keating, Imogen Heap, Juana Molina and Kid Beyond) but in general, pre-rehearsed and already thought out pieces of music using live looping feel as sterile to me as people push playing on DATs, I-pods, CDs, DVDS or computers. I actually really and truly loved sculptured recordings but to me, the live sphere is a different thing. And maybe this is just because I lack the discipline to go to all the work of pre arranging pieces of music when I play, but the last ten years or so of my life have been all improvisational. Of course, one (and specifically, me) run the risk of not having a cogent enough performance or , worst yet in live looping, taking too long to create a piece of music and letting it go on for longer than it is musically interesting for the audience. It's a constant worry for me and I frequently blow it live. I've noticed that a lot of loopers in our community seem to fail to realize that the what feels good to play; what seems like a certain length of time in developing a piece of music is completely different for the audience. Personally, just because I teach a lot of live looping in my hometown, I tell newbies to set up a clock and to force themselves to start, develop and cogentally end a piece of music every five minutes so that they have six pieces of music in a festival set of thirty minutes. It's a tough discipline to do that. I purposefully write set lists with 6 to 7 tableaus in it. I don't know what I'm going to play, but I do take 6 or 8 'sets' of instruments to each gig so that I can keep a found sound performance intriguing. I've discovered is someone has the discipline to play 6 five minute songs in order five times a week that after a month, they are ready to perform a pretty interesting set as a newbie at the festival. ****** Also, and pardon this rambling post, but I"m in a 'waxing philosophic' mode today: I'm writing some new material that is more song oriented and even (damn this is scary to admit in public) singer/songwriter oriented, so I know that I need to figure out a way that I can compromise my desire for spontaneity and improvisation with composed (if not arranged) material. It's a really challenging thing for me. Frankly, it really scares me because it's so different from the freedom I've had for ten years, but I also am really hearing some new things with my new foray into stringed instruments. SOOOOO, pros and cons..................what do y'all like and/or dislike about pre arranged live looping shows and what do you like or dislike about pure improvisational shows.
