The ex-wife of bandmate John Phillips helped to create the sound of California.
The quartet's debut album displayed their unique ability to own songs across a wide range of pop styles, both their compositions and covers.
The album was a gold-certified No.2 hit in the US, spending spent over a year on the bestsellers.
In little more than two initial years of success, the creative intensity of The Mamas and the Papas created a timeless songbook.
The LP will also be available on opaque yellow vinyl exclusively at uDiscover Music and Sound of Vinyl.
The vocal quartet were on the June 22, 1968 edition to sing 'Twelve Thirty,' a US hit single the year before.
The track evoked the Summer of Love of a few months earlier and made lyrical reference to The Beatles.
The folk rock band was comprised of John Phillips, Denny Doherty, Cass Elliot (aka Mama Cass), and Michelle Phillips.
The summer of 1966 brought the Californian quartet's next hit.
As the last surviving member of pop harmony giants the Mamas and the Papas, we celebrate Michelle Phillips' musical legacy on her birthday 4 June 1944.
