Check out the Giants Causeway and Newgrange burial site.
Another fine video featuring the Giant's Causeway and the genius idea of using it as a drumkit.. Easter by Marillion. Saw them in Montreal for 3 shows a few weeks ago and this was in the set, they actually played the album it is on (Season's End) in its entirety on night 3. Gets better every time. Moving lyrics and an epic guitar solo.
3 different sets over 3 nights including two whole album playthroughs. An amazing achievement. With their large and dense soundscapes just keeping those 7 or so hours of music in your head without it dribbling out of your ears is a challenge.
