After playing the original Guitar Hero game for PS2, I checked into some of the artists of songs I like and found that they had done even cooler stuff. Here is a list of the artists and the first song I heard from them on Guitar Hero.
Audioslave - Cochise
Eric Clapton (Cream) - Crossroads
Boston - More Than a Feeling
ZZ Top - Sharp Dressed Man
Deep Purple - Smoke on the Water
The Donnas - Take It Off
Stevie Ray Vaughn - Texas Flood
David Bowie - Ziggy Stardust
Out of those, ZZ Top and Stevie Ray Vaughn are my favorites. I had no idea that ZZ Top did Gimme All Your Lovin' (which I had only heard in The Santa Clause) or La Grange.
I had never even heard of Stevie Ray Vaughn before. Now, he's probably my favorite artist, which sucks because he's dead. So I just use YouTube to see him live! My favorite SRV song is probably Scuttle Buttin'.
What's the strangest way you've discovered a new artist?
