The first ✨ ROCKSTAR ✨ of the world

Not entirely sure what you're asking. Karajan was a very famous Beethoven conductor, in large part because he was the conductor of the most famous orchestra in the world at the time when recording technology was starting to get good (50s/60s), so his 60s Beethoven cycle was owned by pretty much everyone who had interest in classical music and owned a record player. He also recorded the cycle in every decade from the 50s to the 80s, with each one having their strengths and weaknesses. I prefer Furtwangler in Beethoven, but his recordings are in poor sound compared to Karajan's. 

Also, for the first "rockstar" in the world I might nominate Liszt. The stories you hear about him are very similar to what you hear about modern rockstars. Even back then I don't think composers quite got the rockstar attention that performers did.

Depends on the day, and it's also really hard picking between his symphonies, chamber works, and piano sonatas because they're so different. But if I had to live with just one:


That slow movement is just about the most profoundly moving and spiritual piece of music I know of. Never fails to leave me in a puddle. The rest of the movements are fantastic as well.
