What to read after Czeslaw Niemen's Niemen Enigmatic?

Niemen Enigmatic is the fourth album in the career of Czeslaw Niemen, arguably one of the greatest Polish musicians of all time (from pop and rock to jazz-rock and avant-garde). The book asks how significant was this album? How enduring is its popularity? Has the popularity and meanings changed over time? It does this by unpacking its production, which was unprecedented in the history of the Polish popular music due to its large number of musicians with varied backgrounds, including progressive rock, mixing jazz, rock and soul with classical music. It also examines its appeal to different segments of Polish population, and failure to reach foreign audiences, despite Niemen himself privileging this album, especially its centrepiece, Bema pamieci zalobny rapsod (Mournful Rhapsody in Memoriam of Bem aka A Funeral Rhapsody in Memory of General Bem aka Mourner's Rhapsody), in his attempt to make a career abroad.
