April 8th is National Music Day, and love:live music is a collection of free live music events to celebrate the day. Here's the current list of events in Dublin. I'm planning to go to the Piperlink recital. Piperlink combines uilleann pipe music with a spoken-word history of the pipes.
The organisers of love:live, Music Network, are very keen to promote not just passive listening to music but also participation - there are many skilled amateur musicians who keep their musical abilities hidden away. If you're interested, there's still time to submit an event for National Music Day. I particularly liked the suggestion of live music being played in the workplace.
