Table schema:
CREATE TABLE concert (stadium_id VARCHAR, year INTEGER); CREATE TABLE stadium (name VARCHAR, capacity VARCHAR, stadium_id VARCHAR)

Question: What is the name and capacity of the stadium with the most concerts after 2013 ?
SQL: SELECT t2.name, t2.capacity FROM concert AS t1 JOIN stadium AS t2 ON t1.stadium_id = t2.stadium_id WHERE t1.year > 2013 GROUP BY t2.stadium_id ORDER BY COUNT(*) DESC LIMIT 1
