One of the delights in life is to be surprised by something that has become familiar or even old hat, or to discover something grand you missed the first few times around. Somewhere along the way, I am sure I heard the fourth and final movement of Beethoven's Fifth Symphony. I am sure it was in the recordings I grew up with. I am sure I sat in the Lyric or the Meyerhoff once upon a time and heard the BSO perform it, either under Commissiona or Zinman. So, unless I walked out or fell asleep, I would have heard the fourth movement.

I just never heard it as I heard it Sunday morning -- and on a car radio no less.

It is a breathtaking piece of heroic music, and I am sure it has been overlooked by the average classical music fan.

We are very familiar with the 5th Symphony and particularly the first movement, and particularly the first four notes of the first movement.

But, as Jonathan Palevsky, the host and program director of WBJC-FM (91.5) who aired the fourth movement Sunday morning, confirmed, it is, indeed, not unusual to find that music lovers have missed the fourth of Ludwig's 5th.

That the piece could move me, coming through a mediocre sound system in a car on a highway, says a lot for the recording, and Palevsky believes it's one of the greatest -- the 1975 performance by Carlos Kleiber and the Vienna Symphony. Turns out to be one of the greatest recordings of anything ever. You can look it up.
