You are not toast, not yet. However, you may want to take action soon.
For 15 years, I used my business name; another company trademarked the name in 2011. Am I toast?

In short, the trademark is registered. What is your obligation to respect their trademark rights? What is possibility of canceling their trademark? Likely, you will want help from an attorney that understands trademark law.
Do we change our band name or fight trademark holder?

Wow. Success brings copycats and people who desire to trade on your name. You need to determine what facts that you know, what facts you can prove, and a review of the trademark record.
