Blood, Sweat, and Tears is one of the best horn bands of the 70s. Trumpeters in the group include original members Randy Brecker and Jerry Weiss, as well as legendary Lew Soloff and Chuck Winfield. Here are a few classics. If you don’t know the band, I highly recommend this album, a compilation of their biggest hits.
There’s a whole chapter of trumpet listening recommendations from all genres in Sound the Trumpet: How to Blow Your Own Horn.
