2012, In astrological terms, the transit of Venus is when the planet passes between the Sun and the Earth, displaying as a black disc moving across the sun for a period of several hours to stargazers around the globe. The occurrence happens approximately every 240 years or so and is not entirely predictable making it a very rare phenomena. In musical lingo, 'Transit of Venus' marks the return of Canadian rockers Three Days Grace and the follow up to their 2009 disc 'Life Starts Now.' Transit of Venus, the fourth album from Canadian rockers Three Days Grace, finds them elevating their driving sound into something altogether more refined than anything they've done before.
