Stevie Wonder was a regular part of my Radio 1-filled days back in the 70s. I liked some of his singles a great deal; others were just ok. Always a good tune. But he never really figured for me in terms of albums (unsurprisingly, I wasn't buying albums when he was making his most celebrated ones).
So I'm late to the party - but I'm really glad I made it. Especially for the sake of Innervisions. It's got great tunes, anger that is gritty and righteous anger and a shot of (somewhat unfocussed) hope. The kind of album you don't play for ages and, when you give it a spin, wonder why on earth you haven't.
