Getting Up Guide: Lilith 2.0, Herculean disco, America's day

What are your plans tonight? The Getting Up Guide is here to help you answer that question. Here's what's happening on Tuesday:

Lilith Fair

No, you haven't been asleep since 1999. The year is, in fact, 2010 and Lilith Fair is back after an nine-year hiatus. If you attended any of the festival's original shows, you'll be happy to see Sarah McLachlan back atop the bill; she's joined by a crop of established vets and up-and-comers alike, including the Indigo Girls, Court Yard Hounds, Cat Power, Sara Bareilles, Beth Orton, Chairlift and others for an all-day affair at Merriweather Post Pavilion. The music begins at 2:30 p.m. so you might want to start planning your escape from work right now.

Hercules and Love Affair

The disco-pop brainchild of New York-based DJ Andy Butler, Hercules and Love Affair is an exercise in dancing and feeling. The DFA Records signees (the label run by LCD Soundsystem's James Murphy) are experts when it comes to producing some of the most emotionally affecting disco you'll ever joyously bounce along with. Nevertheless, the music overrides the message and it's quite possible the Rock and Roll Hotel's roof will come off when "Blind" comes on sometime after 8 p.m.

Chad America's Birthday Party

When our birthday rolls around, most of us secretly hope that our friends will throw a really cool party or purchase the perfect gift. Not Black Cat bartender Chad America. He's a take-charge kind of guy who organizes his own party, booking a couple of bands to play the club and inviting all and sundry to drop by to wish him well on his 33rd birthday. This year's entertainment comes from the snotty garage rock of Stop Worrying and Love the Bomb, the Electricutions' '70s-inspired political punk and the Drains. As always, there's no cover charge.
