Originally scheduled to perform a few weeks ago, a snowstorm bounding through north Georgia forced the duo ScrapOMatic to return another time.

Well, that time has come.

Mike Mattison and Paul Olsen comprise the duo, which has recorded three acclaimed blues/roots albums since 2002. Both were raised in the twin cities of Minneapolis and St. Paul, Minn., where Mattison started his career as a bass fiddle player. He was obsessed with Ray Charles, who his mother took him to see seven times by the time Mattison turned 11. He later attended Harvard University, where he served as vice president of the Harvard Lampoon humor magazine and graduated cum laude. Olsen started playing guitar in the second grade and by age 17 he was the sidekick to local bluesman Little Bobby E.

The two met during a concert in Minneapolis, and a musical partnership was born.

Mattison, also the front man for The Derek Trucks Band since 2002, told The Times in a phone interview in January that singing has always just come naturally.

Over the years he has modeled his singing style after blues artists Nina Simone and Curtis Mayfield, among others. The Derek Trucks Band was recently up for a Grammy for its album, “Already Free!”  in the best contemporary blues album category.
