Joshua Bell — arguably the most celebrated violinist alive today — is bringing a live recital to San Francisco, and tickets have been available with a promotional window that closes March 31. If you haven't grabbed yours yet, consider this your nudge.

For those unfamiliar, Bell is the kind of artist who makes you rethink what a single instrument can do. He's a Grammy winner, a former child prodigy, and the guy who famously played a $3.5 million Stradivarius in a Washington D.C. Metro station in 2007 while nearly everyone walked right past him. It was a social experiment, and it proved something we already suspected: people are terrible at recognizing value when it's not packaged with a price tag and a velvet rope.

If you're a classical music fan — or even just curious — this is the kind of event that reminds you why live performance still matters. Don't sleep on it. The ticket sale ends soon.
