Monday

>>Provided these thunderstorms pass us by in time, the place to be tonight is Fort Reno. First off, it’s free, and we know everyone’s wallets are light from all that gas you’re having to put in the car just to make a run to the beach. Second, recent Three Stars alums Garland of Hours are taking the stage, along with The Aerialist, and the excellently named Lady in the Radiator. 7:15 p.m., $0.

>>On the other side of the spectrum, you can drop a pretty penny for some scary sounds on a summer night. Marilyn Manson and Slayer will do their best to pound your eardrums into submission tonight at Merriweather. Gates at 5:30 p.m., $30-$45.

Tuesday

>> Local favorite and former DCist interview subject Paul Michel, headlines a backstage show at the Black Cat. Michel’s intimate singer-songwriter sound should suit the small room perfectly. With Tereu Tereu and Rocky’s Revival. 9 p.m., $8.

>>Brightest Young Things appear to be big fans of Donny Hue and the Colors, a band that brings together members of the Carlsonics, Nethers, Washington Social Club and Meredith Bragg. After reading their description, we think we might be, too. You can get a taste for free at the Kennedy Center’s Millenium stage Tuesday evening. Because we know you’re wondering what an autoharp will sound like in a rock band. 6 p.m., $0.

>>Longtime cult faves Guster take the Filene Center stage at Wolftrap along with singer/songwriter Pete Yorn. 7:30 p.m., $25-$36.
