"Bra" (Cymande)

Cymande, which means "dove of peace" in West Indian patois, is a London-based band consisting of Caribbean-born musicians.  During its original run from 1971-74 (the band recently reformed in 2014), Cymande set itself apart from its contemporaries by blending elements of jazz, hard rock, and Afro-Caribbean music into its special brand of funk.
Its self-titled debut album from 1972 is a sweaty, 40-minute workout from beginning to end, featuring songs built around spare, but deep, grooves and intricate polyrhythms.  (Picture if the band War had come from Kingston, Jamaica, instead of Southern California, and that's the vibe of this album.)
One of the standout tracks on the album is the song "Bra" (as in "brother," not the undergarment).  It's exactly 5 minutes of churning, bubbling soul, featuring rippling congas, all manners of percussion (including mouth clicks), and a supremely funky, serpentine back beat.  Those familiar with the De La Soul track "Change in Speak" from 3 Feet High and Rising (1989) and/or Spike Lee's 1994 film Crooklyn no doubt will recognize the song's distinctive bassline and horn riff right away.
At its heart, it's a song of encouragement.  The lyrics express that, no matter what challenges you've faced or are currently facing, it's going to be okay; you are going to succeed.  
It's the kind of positive message and uplifting groove that we all need from time to time.
