Decades ago, back in college, I was part of a choir that sing Johann Nepomuk David's setting of Veni Creator Spiritus. A lot of people in the choir hated the piece but I loved it. It sounded surreal and fascinating to me.
I had no idea until this week David composed music for the guitar, too. But I was hunting around on the net for guitar music stuff and found out that J. N. David did, in fact, compose a sonata for the guitar.
