Terry Kath was the original guitarist, vocalist and founding member (along with Walter Parazaider, Daniel Seraphine and Lee Loughnane) of the band Chicago.
He contributed to their first album, Chicago Transit Authority (1969) with his composition "Introduction". The song displayed many varied musical styles, including jazz, blues, rock, and pop.
This album also included an experimental guitar piece aptly named "Free Form Guitar", which was reminicent of Jimi Hendrix. The rest of the album displayed master guitar playing almost completely over three of the four sides of the record. The hit "Questions 67 & 68" had incredibly virtuosic guitar lines that became staples of the Chicago sound, and the hit "Beginnings" showed another aspect of his guitar playing — carrying the song in crystal clear rhythm, later emulated by dozens of soft rock bands of the 1970's. But it was in the songs "Poem 58" and "Liberation" that he really revealed all his potential as soloist.
Terry Kath's contribution for the following 10 album releases of the band showed an ever growing musicianship and expanding guitar techniques as can be heard on "The Road," "It Better End Soon, My Friend," and the beautifully scored strings for his "Memories of Love" and its preambles from Chicago II (1970). "Sing a Mean Tune Kid", the suite "An hour in the Shower" and others from Chicago III (1971) gave complete dimension to the album, which also displayed the more sacharine hits by the other members. The times were changing and Chicago's musical direction diversified, but the original go-for-it approach lived on with Kath's compositions and performances through the years. His "Oh, Thank You Great Spirit" from Chicago VIII (1974) was incredibly swift and dynamic, with guitar solos not heard for quite a time in a pop album. Until his last contributions on Chicago XI (1977) this was the outcome of his creativity.
His singing was also a unique feature. The warmth and passion in "Color My World" from Chicago II (1970) or his screaming in the live version of "Free" from Chicago IV (1971) are good examples of this. His contributions to modern guitar may have been overlooked over the years, since the band survived Terry's untimely death on January 23, 1978, and simply continued to make big hits expanding to two more generations of listeners.
Other compositions by Terry Kath:
