The Yardbirds when it came out in February of 1966. Not only were they the group just about every garage band in L.A. wanted to sound like, they also had three of the greatest guitarists in the world playing with them at one time or other. Eric Clapton, Jeff Beck and Jimmy Page left their mark on what was probably one of the most influential bands of the 1960's.
In the off chance you aren't familiar with them (and I've been reminded by several colleagues that no, take nothing for granted) now is a very good time to start.
Shapes Of Things just has 2010 written all over it.
