U2 is and has been my favorite group for over half my life. This mashup almost comes across like a remix, taking U2's Mothers of the Disappeared and adding parts of Dishwalla's Opaline from the album of the same name. Anything off of U2's The Joshua Tree doesn't need an introduction, just cuz it's off the The Joshua Tree. Dishwalla's album Opaline though is an incredible album in its own right. The opening song Opaline sets the tone for 45 minutes of tranquil fury throughout. Highly recommended.
