I got calls from this number every day. Caller ID doesn't show who owns this numbers. A web search shows it's from Philadelphia, and a business number carried by Verizon. Anyone knows who own this?

I believe it's from the Kimmel Center for the Performing Arts. I've gotten several calls from them, too, on my work phone. And they're always after hours (6 p.m.).

I bought tickets for one event 8 months ago, and now I'm sure I'm on their end-of-year fundraising list.

It's the box office at the Kimmel Center, often an automated marketing message.  I've asked them repeatedly to stop calling, but every time I buy a ticket, the calls start again.  Unbelievable.

Yes, It's Philadelphia Orchestra. I called back and the guy said that is telemarketing and we should just ignored it.

Well, I won't go to any Kimmel Center events ever again.  That's a shame for them and for me, but they call so frequently (every day, every other day), never leave a message, and recently one of their calls woke me up when I was very sick and desperately trying to rest.  They apparently aren't aware of a new communication device called email and email marketing to alert interested consumers of what's going on at Kimmel.  To say 'ignore it' is completely inappropriate --- it is very annoying and the wrong way to treat customers.  But I'm glad I found out through this thread who it was, I was about to buy tickets to various events as holiday presents for family and now I know to go elsewhere to spend my money.  Shame on you, Kimmel, what should be a respected arts organization of the highest sophistication, but dragging us back into the 1990's with your extremely annoying telemarketing.
