You must have seen This Is Spinal Tap!
If so, you'll know it's brilliant enough to watch on repeat. And if you haven't, CMB (Cinema Música y Barbacoa) won't judge*. They'll just kindly invite you to an informal film screening that they've organised. Sit back, relax, enjoy the film, music and BBQ on the terrace. What's more, you can show off your musical skills in an air guitar contest; the person with the best riffs wins a box of Bud.
* For those of you who don't know the story, This Is Spinal Tap is an Eighties' mockumentary which follows a band (called Spinal Tap).
Tickets are €7 in advance, and €10 on the day.
