He oversaw hit-yielding sessions with such A&M artists as Burt Bacharach, the Carpenters and TK, and when his own muse called, the studio door was open. He was free of the Tijuana Brass banner, free of the six-month cycle of producing a new album, then touring to support it. Free to explore an intriguing series of sounds and musical situations.

Over the next twenty years, Alpert worked as a producer and with a number of producers; he collaborated with instrumentalists, singers, and composers. His trumpet sound matured and became even more expressive; “It changed. I think I had the same basic sound of the horn but I had an attitude lift,” Alpert laughs. He continued to borrow tastefully from varied sources (Brazilian samba, Bronx hip-hop) and developed a habit of creating music that predicted future trends.
A few examples:

• In 1970, Alpert worked with French composer and arranger Michel Colombier, producing the rock oratorio Wings, an ambitious – and sadly forgotten – groundbreaker that wove together strains of symphonic music with pop and jazz . It was a grandiose project that corralled the talents of dozens of musicians, including singers Bill Medley and Lani Hall, violinist Jean-Luc Ponty and lyricist Paul Williams.
