Help choosing Classical Music LPs

Hi there guys, I just a vinyl lover as many of you already hear from me, but certainly new to the classical music world that one day was far but today is becoming more regular on my TT evenings sessions.
Today I am playing a Joaquin Rodrigo Concierto en Aranjuez. Fantasia para un Gentil Hombre for guitar and orchestra.
Ernesto Bitetti Guitarrist
I do really love this kind of music, I would like to hear from you about what kind of direction I should move looking on drifts stores, on the net etc, I want to increase knowledge and exposure to the great composers.
Basically I want a list of what to buy, known master pieces orchestras etc, I feel blind in front of so many lps with no clue who they are or what might be worth to buy.
Your help highly appreciated,
is all about the music these days for me...

Regards
