I got a note from the band formerly known as Boycrush. They are now known as Quadrillion. They didn't really tell me why the name change happened, or why they picked Quadrillion. Personally, the name Quadrillion reminds me a bit too much of another band.
But, in order to really learn what it means or what it's all about, you can simply ask them at their show at the Monkey Pub (5305 Roosevelt Way NE) on Saturday night.
