Donald Byrd-Ethiopian Knights (1972)

Donald Byrd was one of the most accomplished trumpet players of hard bop, with a prolific career spanning the 1950s and well into the 21st century. With a discography exceeding thirty albums, in addition to collaborating on over a hundred projects and albums for other artists, Byrd compensated for his lack of creative freedom in composition and his limited innovation with works characterized by grand instrumentations and an effective, dynamic jazz sound. At the height of his career, Byrd recorded a series of groove jazz albums now considered classics of the genre. "Ethiopian Knights" was one of them, an album whose enduring popularity has led to countless reissues since its release. Released on the prestigious Blue Note label, this album is divided into two extended jams, quite far removed from the conventions of structured jazz, both exceeding sixteen minutes in length. The band featured Donald Byrd on trumpet, Harold Land on tenor saxophone, and Thurman Green on tenor saxophone. Trombone, Bobby Hutcherson; vibraphone, William Henderson; Fender Rhodes, Joe Sample; organ, Ed Greene; drums, Wilton Felder; bass and guitars Don Peake, David T. Walker and Greg Poree, demonstrate the prodigy of each of them, the versatility, a great cohesion and an irresistible jazz rhythm making this album an essential work of the hard bop genre.

Dies Irae-First (1971)

Dies Irae was a German band formed in 1968 that built a strong reputation through their wild concerts throughout southern Germany and countries like Switzerland and France in the late 1960s and early 1970s, until the prestigious German label PILZ offered them a contract and released their first and only album in 1971. Their lineup consisted of Rainer Wahlman on lead vocals and harmonica, Harald Thoma on guitar and vocals, Joachim Shiff on bass, and Andreas Cornelius on drums. Dies Irae's style was a strange mix of progressive and psychedelic heavy metal with strong influences from dark, heavy blues. Their only album, "First", is a hallucinogenic musical journey with a heavy emphasis on acid guitars and trance-like states, a result of the band members' LSD use. This debut album contained some truly interesting moments, such as the opening heavy rock track "Lucifer", the psychedelic jam "Witches Meeting", the intense heavy rock of "Another Room", and the acid rock of "Trip". After its release, the band gained considerable notoriety, even though most German radio stations refused to play the record due to its connotations of drug use and its links to religious rituals. However, a music video was broadcast on a German television network, providing them with enough publicity to achieve underground and cult status a connotation that persists to this day.

McChurch Soundroom-Delusion (1971)

McChurch Soundroom was an unusual Swiss progressive folk-blues band that released only one album in 1971 (with a rather sinister and unfortunate cover, by the way), before vanishing without a trace. The only information about the band is on the album's back cover, which, aside from the track listing, lists the members: vocalist and flautist Sandy McChurch, keyboardist Alain Veltin, bassist Kurt Hafen, guitarist Heiner Althaus, and drummer Norbert Jud. Their music showcased a heterogeneous sound that drew on German krautrock with elements of jazz and progressive hard rock, fused with British folk and blues. This album, titled "Delusion", was released by the underground label Pilz and showcases the musical eclecticism of McChurch Soundroom. It ranges from sounds reminiscent of early Jethro Tull in the opening track, which lends its name to the album, to complex compositions like "Time Is Flying", superb forays into progressive jazz such as "Trouble", and typical 70s hard rock like "Dream of Drummer". While not an exceptional or particularly original work, its music is nonetheless captivating and features excellent instrumental performances from all its members, especially the flute, guitar, and Hammond organ.
