It's similar to a tequila sunrise, but with a quick splash of blackberry brandy. This was a popular drink among my circle of friends in the mid-1970s or so. I almost forgot about it until I came across it recently. So I thought I would post the recipe here so I wouldn't ever forget about it again. If mixed correctly, the blackberry brandy will slowly settle down through the orange juice layer, which creates uneven or striated colors that are said to resemble a sunset (hence the drink's name).
