If you count yourself among Rush's loyal legion of devoted (and, in some cases, deranged) fans, don't forget that tomorrow is International Rush Day.

Observed every year on December 21st (21/12), Rush fans across "all planets of the solar federation" are encouraged to travel through the barriers of time into the era of "Templevision, Megadon, twin moons and atmospheric domes when city and sky merge into a single plane".

Although International Rush Day was officially launched in 2011, it coincides with the classic 1975 album "2112", which celebrates its 38th anniversary tomorrow.
