Around 1970, two separate developments occurred in popular music. First, some jazz musicians, perhaps interested in garnering more attention and commercial success, began to incorporate elements of rock music (a steady beat, electric instruments) into their music. They blended extended improvisation into a rock-like context to create what was called fusion. Jazz trumpeter Miles Davis pioneered this approach on his recording, Bitches Brew (1970). At the same time, some rock groups emerged that included horn sections made up of jazz-trained musicians to create rock  music that featured complex harmonies and solos that were more jazz than rock in style. Among these groups were Blood, Sweat, and Tears, Chicago, Cold Blood, and the Sons of Champlin. An especially good example of this approach can be heard in BS and T's cover of God Bless the Child. It begins a s a bluesy ballad but in the middle of the song the tempo changes and there are a series of blistering horn solos that are straight out of a jazz disc.

The group Chicago was more pop-oriented than BS and T, but it also featured a horn section on many cuts. Cold Blood was fronted by a knockout vocalist, Lydia Pense, and she was backed by a powerful rhythm section augmented by horns. Other groups with jazz tinges included Earth, Wind and Fire, Ten Wheel Drive,  Steely Dan, Tower of Power, and Dreams.

Ten Wheel Drive formed in the late sixties and featured singer Genya Ravan.  Their song "How Long Before I'm Gone" is a great example of the excesses that sometimes afflicted horn bands. Nearly seven minutes long, it has four distinct sections and changes character several times.
