I have that on CD and there's more cover versions on it then I thought, including a 21 minutes cover of Smokey Robinson's "Get Ready" (I'm on my way, but not really in a hurry to get there - or so it seems).
Should we call this funk-rock?
"Rare Earth’s music straddles genres and defies categorisation, slipping seamlessly between the two seemingly disparate worlds of classic rock and R&B. This careful balancing act is a rarity even now and was a near impossibility in the colour-segregated 60s when Rare Earth began their journey. Groundbreakers and pioneers, this post-racial band should have been the first of many. Instead, they remained one of a kind." https://www.loudersound.com/features/cult-heroes-rare-earth-motowns-funkiest-white-band
