Metallica is a popular heavy metal band that was started in 1981.  While I don't listen to their music I do like their logo.  The M and the A make the logo interesting to look at, plus this is one of the few logos for a band that I have written about, that only uses font for their logo.  The logo was created in the 1980s when the band was first starting out. I don't know who designed the logo though.  In my opinion the logo seemed ahead of its time when it was created in the 80's.  This is because it looks like something you would see nowadays.
