On Rush’s “Time Machine Tour” the band used Alchemy Symbols on their tour logo and on the clock on the cover of the program…
Geddy Lee even put the alchemical symbol for Amalgamation on his bass that was used for the “U” in Rush on the logo…
The Alchemy Symbols and meanings are very confusing so I’m not gonna attempt to figure it all out but if anyone knows more about it, please let us know…
From Wikipedia:
"An amalgam is a substance formed by the reaction of mercury with another metal."
Seeing that they were on Mercury records for a good part of their career, perhaps the use of this symbol was intentional – they are a clever bunch!
