Sometimes there's only one type of music I want to hear, especially in times of stress, and that's the kind of superficially undemanding – but deceptively complex and expertly played - music from the late 60s/early 70s that is Sunshine Pop. Sure, it was the industry's non-challenging response to the drug-oriented explosion of psychedelia and hippiedom - lyrical concerns centred instead on (surprise!) sunshine, not to mention rainy days and Sundays, with a side order of circuses and clowns; it was never cool, and I realise that to many people it might seem like the most anodyne fare imaginable, but to me it feels like a warm musical hug. Here are a few favourites of many:
Northern Lights (from 1973!)
