I'm in the process of expanding my music library. I'm coming from a heavy rock to black metal background. I've always been interested in classical music though, but never got into it. I'm having a hard time knowing what to look for. I'm a big fan of Wagner. I'm currently accumulating all the Operas he did. I also have most of Bach done. I really like the "Brandenburgische Konzerte". Also many of the solo piano pieces are to my taste. Though not "old" classic, i really enjoy listening to Ludvico Einaudi. What are the "basics" when talking Opera? What should i look for? Any composers you'd recommend i have a look at? I know i only scrached the surface and went straight to the "mainstream", so getting more into the "meat" of it is what i want. Also, i know that in classical recordings the specific performer and recording are important. I currently don't care that much for the quality of the recording. It's nice if it's good, but i'm more about the content atm.
