Yes, the double exclamation mark is appropriate in my humble opinion.
Maceo Parker is playing the Temple Bar Music Centre on April 24th.
If you dont know who Maceo is, he is a legendary (i dont use the word lightly) saxaphone player. Has with some fantastic artists such as James Brown, Funkadelic and Prince. Has had a decent solo career for a while too.
If you want a great night out, get a ticket, seriously.....go, get a ticket.
