Is it possible to disassemble an Ikea BILLY bookshelf to move it? Iif so is it easy to do?
I think it could be done, provided they didn't glue any dowels when they put it together. You may want pliers to yank the dowels out, and take a small piece of wood to protect the bookcase if you have to hit any parts with a hammer to disassemble them. The only glitch I can see, really, is taking apart those two-part fasteners, the ones with with a sort of screw that slides in and is then fastened with a little metal piece that has a slot in it for a screwdriver. Those can be difficult to unfasten. Sometimes you have to turn stuff upside down and whack it good to get those out, or if you have a small very strong magnet, that might work. There are 12 of them in the instructions for the Billy 80" case. If you have time, patience, a logical mind and the right tools you should be able to do it. Keep in mind that even if you take them apart you'll still have the side panels at 80" long so you'll probably still have to leave the back of the car open to fit them in, but at least it'll be possible to carry the parts by yourself. Carrying the whole book case by yourself would be ridiculous, they won't take much flexing before they start to break. If you break any hardware you should be able to find it again at Home Depot or a woodworkers supply place if not from Ikea.
Really Dark Classical Composers?
Look for Alban Berg's 3 Pieces for Orchestra. Really abstract yet dark texture to his music. Gustav Holst's Mars movement from "The Planets" is a very moving piece but it does have some brighter passages. Stravinsky's Sacrificial Dance form "The Rite of Spring" is very unpredictable and dark. Try listening to the entire piece and explore the surprises.
