So I am way late to the party but have just started listening to a fabulous band you probably already know - "Snow Patrol". Loving their last album from 2011 and just starting to delve into their back catalog. Some great passionate and heartfelt music. I found a song called "Hands Open" which has a some cool fairly simple riffs in drop d tuning. After I learned the song I came up with this riff. The only real similarity is the tuning however. You should totally check out the song though its fun to play. Hope you dig the riff. If you have problems following the video I can tab it out if requested. The tracking on the video is a bit weird but the audio should be cool.
