Puerto Rico Heineken JazzFest in San Juan
Held each March in San Juan, the Puerto Rico Heineken JazzFest is one of the island's most established annual music festivals, bringing international and local jazz artists to venues in the capital as part of a busy San Juan festival calendar that also includes the Casals Festival and Puerto Rico Comic Con.
San Juan's cultural calendar is dense enough that most of its annual festivals compete for space rather than a single obvious month.
