Listened to some new mashups lately and by far my favourite was a very recent one made by DJ Schmolli.
Itīs a mix of Iron Maiden with Monkees and itīs completely hilarious:

The Trooper Believer


On a tad more serious note, Iīm really enjoying Philip Glassī Akhnaten (1984) which is as good as modern opera gets.
Captivating atmosphere and overfilled with tension.

Act Ii- Scene 2- Akhnaten And Nefertiti


Also, Planxty, more precisely, their debut from 1973.
Some of the best celtic folk music ever recorded.

Follow Me Up to Carlow

Here theyīre performing one song from the album live:
The Blacksmith
