Don’t miss the curtain.

Because Martín is a big draw, concerts are free and venues are small, getting a seat may take some doing.

Here’s how to avoid disappointment:

San Germán: First come, first served. Arrive 45 minutes early. Reaching the museum is like climbing a pyramid. Anyone with mobility issues should pass.

Mayagüez: Easy access, small capacity. The early bird gets the clarinet. Preregistration is a must. Use Jotform or telephone (787) 986-7850 to commit to a seat.

San Juan: Arrive a half-hour early. Maximum seating capacity is 100.
