Name a few albums which helped determine your musical tastes

Sgt Pepper Beatles
Freak Out Zappa
Yer Album James Gang

To the person who asked, "Doesn't anyone like Creedence (Clearwater Revival)?I will repeat the valid criticism of my prior post:  They were just fine, but they certainly did not influence me in any way, which was the title question to this thread. 

To the person who claims that classical and jazz are not something one necessarily needs to "Shoe Off) an audiophile system.  BfS!  Nothing demonstrates our systems' superiority as much as the tightness of an acoustic bass, or the accurate reproduction of acoustic instruments, no matter how many (in the case of classical) how many instruments there are.  Still, for my rocker friend, I am obligate to rock out with The Chili Peppers, Audioslave, Body Count, but especially Santana's Supernatural album.  For extreme acoustic sound, it is hard to beat The Violent Femmes white CD of their double album.

Queen - The Works (that's when I fell in love with them)
Rage Against The Machine - Self Titled (I never heard anything like it)
Pearl Jam - Ten (My favorite grunge era album)
2 Live Crew - Me So Horny (single) (I didn't know one could sing those lyrics)
Bob Dylan - Blood On The Tracks (Perfection)
U2 - Achtung Baby (A complete 180 from Joshua Tree. Masterpiece.)
AC/DC - Back in Black (Perfection)

To name a few... 

Violent Femmes - Debut album
Elvis Costello - My Aim is True
The Clash - Sandinista
Juana Molina - Son
Yo La Tengo - I Can Hear the Heart Beating as One
Willie Nelson - Shotgun Willie
Califone - Roots & Crowns
Lhasa De Sela - The Living Road
