Ed Sheeran already had some album promotion under his belt before his plans took a turn this week, as Tuesday morning saw the release of a “Tiny Desk” video concert, filmed for the NPR franchise, including several songs the “=” album (pronounced “equals”) that/s coming out Friday. While Sheeran has become used to performing in front of tens of thousands of fans worldwide, this performance was unique for the four-time Grammy-award winner. In most instances, Sheeran performs alone on stage, using only a microphone, his trusty guitar, and a looping machine. His "Tiny Desk (Home) Concert," however, saw Sheeran perform with a cast of 15 world-class musicians—including the mastermind himself, Adam Blackstone, on bass guitar. He performed five songs, “Shivers,” “Make It Rain,” “Overpass Graffiti,” “Visiting Hours,” and “Bad Habits,” all from his upcoming fourth studio album “= (Equals).” Especially, “Overpass Graffiti” is an unreleased song and is the first-ever performance. The song will be released this Friday (October 29). “Make It Rain” is a cover of Northern Irish singer Foy Vance. Ed Sheeran recorded the song for the television series “Sons of Anarchy” in 2014.
