Thanks for posting this link, keberoxu. You've made my day.

Sheila Blanco mentioned St Matthew Passion:

This was one of the first LP's I bought in my life, when I was a very impoverished student. I first heard this particular piece on a tiny transistor radio. I was sitting in the sun in the doorway of my tiny, grotty student flat and this tinny little radio was playing the most beautiful piece of music I had ever heard in my life.

Thijs Van Leer - Erbarme Dich from 'St Matthew Passion' BWV 244

It wasn't until a couple of years later when I moved into a student share house with someone who howned a record player that I could listen to that piece of music again but I hung onto that amazing revelatory musical memory until I could hear it again.
