One of the things that I'm personally looking forward to is .. Progress. Innovation. New techniques. New music. New style. Something different.
In these hard economic times, necessity (the old mother of invention) will bring us some stuff, some culture, some style that we have yet to experience. It might be half-recycled. It might be a quarter-replay of some earlier motif. But something new will come, because like I sorta said - it don't cost anything.
Run-DMC, rap music and hip-hop came out of the late 1970s, early 1980s. Guitar became electrified in the late part of the Great Depression of the 1930s. What will come from the recession/depression of 2008-09? Only time will tell.
