Chicago: Walter Parazaider (saxes, flute, clarinet, vocals), Lee Loughnane (trumpet, vocals), James Pankow (trombone), Terry Kath (electric guitar, vocals), Robert Lamm (keyboards, vocals), Peter Cetera (electric bass, vocals) and Danny Seraphine (drums). From the album Chicago II (1970).

In 1977, Chicago released Chicago XI, which reached fourth position in the charts and was certified platinum record. It features Cetera’s ballad “Baby, What a Big Surprise” sung by himself, in which Parazaider plays the flute in the introduction, Carl Wilson of The Beach Boys participates in the choirs and Loughnane plays the piccolo trumpet; it became fourth on the Billboard Hot 100. In addition to recording and touring tirelessly during the 1970s, in 1973 the band also appeared in the movie Electra Glide in Blue, produced and directed by Jim Guercio, and collaborated on the soundtrack, as well as being presented on numerous television programs.

In 1978 Chicago split from Jim Guercio and Kath shot himself with a gun playing Russian roulette. These events caused a deep crisis in the group that lasted until 1983. To replace Kath, after listening to a number of guitarists, in the end they chose Donnie Dacus, singer, guitarist of great talent, actor and writer, and who has worked with such well-known musicians as Elton John, John Lennon, Neil Joung, the band Deep Purple and many others. The first album in which he participated was Hot Streets, produced by Phil Ramone, that represented the beginning of a new period for the group, since in the album we find disco music, pop and ballads, and in its cover doesn’t display its logo with a number, but the title with a photo of the group and the logo being smaller.

The two best-selling songs were Pankow’s “Alive Again” sung by Cetera that tells the story of a lonely man who finds meaning in his life when he meets a woman who truly loves him, and “No Tell Lover” written by Loughnane, Cetera and Seraphine, and sung by Dacus and Cetera.
