Lit will light it up this week at General Duffy's Waterhole in Redmond.

The summer concert series at General Duffy’s Waterhole in Redmond ramps up this weekend with two big shows, one for the rock fans and one for the country lovers.

On Saturday, the Duffy’s stage will host the California alt-rock band Lit, who sold more than a million copies of their 1999 album “A Place in the Sun” thanks largely to their biggest hit, “My Own Worst Enemy” — a poppy, punky song with a great chorus that has aged better than a lot of the rock hits from the post-grunge era. These days, the band is gearing up for the release of their seventh album, “Tastes Like Gold.”

Also, indestructible Oregon prog-rock faves Floater will open Saturday’s show.

On Sunday, General Duffy’s will welcome Aaron Lewis and the Stateliners, a country band fronted by Aaron Lewis, who was (and is) the lead vocalist for the 2000s nu-metal band Staind. Since around 2010, he has also pursued a career in country music, and he’s touring behind his most recent solo album, “Frayed at Both Ends.”

Openers include Toast and Jam, Sleepless Truckers and Jason Nichols.

Lit, with Floater: $45-$105, 6 p.m. Saturday, gates open 4 p.m.

Aaron Lewis and the Stateliners: $100-$200, 6 p.m. Sunday, gates open 4 p.m.
