When U2 released The Joshua Tree in 1987, it was a time when some of the U.S. was politically divided under President Ronald Reagan’s administration among other sociopolitical turbulence around the world. Thirty years later and with more than 25 million album copies sold, the album remains oddly relevant as the U.S. is politically divided again under a different administration and other global turmoil such as the problems in Venezuela, the Syrian refugee crisis and most recently an ISIS-led attack on Ariana Grande’s concert in Manchester.
