Ravel's Bolero entrances me every single time.
I close my eyes...and I get completely removed from reality, fascinated, following the gradual buildup of music like I'm looking at an endless Oriental procession...colorful clothes and exotic smells...flame-eaters...belly dancers...followed by pumas on a leash...tigers and cheetahs....culminating in two giant elephants...and then a sharp nothing.
Never ceases to make me forget for a few minutes whatever boring or irritating something I've been doing the moment before the music started LOL
