LaMonte McLemore, a founding member of the 5th Dimension, the sleek, genre-blurring vocal quintet whose soaring Top 10 hits 'Up, Up and Away' and 'Aquarius/Let the Sunshine In' became carefree anthems of hippie-era idealism, died on Feb. 3 at his home in Las Vegas. He was 90. The 5th Dimension was a commercial force, notching 20 Top 40 singles on the Billboard Hot 100 chart from 1969 to 1972, including seven in the Top 10s and two chart toppers: 'Aquarius' and 'Wedding Bell Blues.'

Why it matters

The 5th Dimension's smooth, genre-blending sound and hits like 'Up, Up and Away' and 'Aquarius' became emblematic of the carefree, optimistic spirit of the late 1960s and early 1970s. As one of the founding members, LaMonte McLemore's passing marks the end of an era for the influential vocal group.

The details

McLemore co-founded the 5th Dimension in 1965 with friends Ron Townson and Billy Davis Jr., later bringing in Marilyn McCoo and Florence LaRue. The group's sound incorporated elements of R&B, jazz, easy listening and even light opera, creating a 'champagne soul' blend that led to critical barbs about not being 'Black enough.' However, McLemore maintained that the group's widespread appeal was intentional, as they 'wanted to do something fresh, and bring all people together' with their unique harmonies and positive messages.
