"heaven's War"

To the ancients, the heavens were filled with awe and wonder. Looking out into space inspired fear, superstitions and the building of massive monuments like Stonehenge. Now, we examine the greatest mysteries of the past to see if they can finally be solved by modern science.

The Journey Home: Live from the Kennedy Center. Inspired by the 100th anniversary of the end of WWI, the concert, which sold-out at the time, explores timeless themes of longing, loss, love, and the search for peace in the wake of catastrophe. Musical selections range from Schubert's Der Wanderer, to Vaughan Williams' Songs of Travel, as well as popular tunes and art songs by composers and poets who died in the war. The concert is performed by Grammy Award winning baritone, John Brancy, and pianist (and host of NPR’s From the Top), Peter Dugan in a 2018 live performance from the Kennedy Center’s Terrace Theater. The concert was presented by Vocal Arts DC and the General Delegation of Flanders to the United States. Brancy and Dugan will also release a single and music video from their performance of, “Where Have All the Flowers Gone,” from the album.

Essential: a masterpiece of progressive rock music.
It took a lot of money to keep up with the flood of albums released after "Sgt Pepper", so you didn't waste money on albums by South African bands.
