There's a final song from an albul "Delta machine" (2013). It has blues influence,
listen to the song and try to catch wright rhythm :)
INTRO & VERSE riff (4/4 key Am):A|--------------------|--------------------|B|--------------------|--------------------|G|--------7(b)--------|--------------------|D|-----7------7-5-7---|--------------------|A|--------------------|-3(b)-0-3(b)-0------|E|-5------------------|--------------------|
PRE-CHORUS (6/4): G E G Fm
INSTRUMENTAL (4/4): Am (riff)
CHORUS (6/4): Fm C Dm
That's all!
Good luck! :)
