Rare Earth-Ma (1973)

Rare Earth's sixth album was preceded by four excellent studio works and a sensational double live album, and became another of their great works thanks to a series of songs full of blues rock reminiscent of funk and soul. "Ma" was produced by one of the producers of the Motown label, Norman Whitfield, who in turn was co-author of some of the album's songs, which would provide it with the characteristic sound of the black bands of the legendary Detroit label. The line-up of Rare Earth for this new album was significantly different from that of their first works, said line-up was composed of Gil Bridges (saxophone, flute and vocals), Peter Hoorebelke (drums and vocals), Ray Monette (guitar and vocals), Mark Olson (keyboards and vocals), Pete Rivera (drums and vocals) and Mike Urso (bass and vocals). The seventeen-minute repetitive guitar riff on the psychedelic and sublime “Ma” is the high point of this album, a track that contrasts with the Zeppelin-like hard rock “Hum Along and Dance,” the soul-funk feel of “Big John is My Name,” and the experimental “Come With Me.” Although it did not have the same media or commercial impact as other previous works, “Ma” was considered one of the cult albums in the underground and over time became one of Rare Earth’s most popular albums.

Electromagnets-Electromagnets (1974)

Electromagnets was an interesting jazz-rock band known for having a very young Eric Johnson in its line-up, who was already showing signs of becoming one of the great jazz and blues rock guitarists. Originally formed under the name Aussenhorowitz in 1974 by keyboardist Stephen Barber and drummer Bill Maddox, they were soon joined by bassist Kyle Brock and guitarist Eric Johnson, changing the name to the definitive Electromagnets. That same year and under the EGM Records label they recorded their self-titled debut album, and ultimately their only release, where they showcase the instrumental virtuosity of the four musicians, especially Barber's skillful and sinuous jazz keyboards and Johnson's eclectic guitar sounds. Tracks like the funk rock “Hawaiian Punch”, the energetic jazz rock “Dry Ice” or the dynamic jazz fusion “Blackhole” show the outstanding mastery of Electromagnets, which together with an excellent production is among the highlights of jazz rock in the mid-seventies, almost at the level of the great bands of the genre such as Weather Report or Return to Forever.
