Chicago pop-ensemble The 1900’s channel a time that its fans probably aren’t familiar with, when FM radio swooned youth with its catchy, early psychedelic hits of the '60s and '70s. With modern radio stuck in a corporate rut, the 1900’s produce light and refreshing folk-pop without being pretentious. Oftentimes featuring horns and strings during their live shows, the outcome is impressive — much like the buzzworthy septet's long-awaited debut EP, Plume Delivery.

With The Libertines relegated to woulda-shoulda-coulda-been tales of flash-in-the-pan brilliance (now that the former members spend their time dodging cops and chasing models), the U.K. was left with a blaring void of sloppy, jangle rock. Enter the swaggering pub tunes of the brothers Jarman. The trio’s rough-and-tumble guitar rock on its third LP Men’s Needs, Women’s Needs, Whatever awakens and picks up right where the band’s previous boozy anthems were passed out.

At age 11, Dax Riggs and his mother were Jehovah’s Witnesses warning neighbors of the Armageddon. Then he saw David Lynch’s The Elephantman and realized there was no God and moved in with his dad instead. Since then Riggs has started and ended many musical projects, most famously deadboy & The Elephantmen with Tessie Brunet. Now sans Tessie and the wordy moniker, Riggs is releasing the same type of blues-y rock that is just as good, if not better, than his previous work.

Since forming in 2005, The Graduate is propelling beyond local fame. In April the Springfield, Illinois band released its full-length debut, Anhedonia, on the Icon MES label. Although they define anhedonia as 'a lack of emotion and the idea of just existing', the 5-some's pop rock makes for a pleasurable listen. Their sound isn't too serious or too heavy; nor is it too light or too poppy. One might say it just ‘is'. (Sunday, 11:15-12:00, BMI Stage) --text: Jen Fischer--photo: Chris Strong

Following in the otherwise embarrassing tradition of actors-turned-musicians is Juliette Lewis, everyone’s favorite "Natural Born Killer." Although in Juliette’s case, she has legitimate musicians to back her up. Juliette takes the stage like a Joan Jett-in-training, complete with energetic movement and snarling lyrics while her band literally "rocks out" in the background. Their second album, Four on the Floor, welcomed media acclaim while their live tour continues to remind us that the guitar is not a wimpy instrument.

Adding international flair to the fest is this quintet hailing from Monterrey, Mexico. The group coalesced in 2000 and found success after winning a Battle of the Bands competition. Their self-titled debut served up a melee of sultry Latin, electronic, and rock music sung both in Spanish and English — while their sophomore album, Atlas, supplied the infectious "Presidente" and "Headphonist." One may not understand what they’re saying, so just follow the potent rhythms. (Sunday, 11:30-12:15, MySpace Stage) --text: Garin Pirnia--photo: Ricardo Trabulsi

If you’re into taking in a lot at once (which you must be to attend Lollapalooza), save some room for MrNorth. These boys are like the Santa Claus of bands, somehow handing out a sonic gift that covers everything on everyone’s wish list. Their latest release, Fear & Desire, throws contrast on U2, puts punk in fast forward, and restores new wave to when it was, well, new. Merry listening.

The resurgence of '60s-style indie pop continues with the Postmarks’ self-titled debut — a dreamy, sugar-coated soundtrack for slow-moving days. Half-whispered female vocals from Tim Yehezkely are the trademark here, guiding this Miami 3-piece. The group presents a tender, romantic take on the finer things in life, tiptoeing around the trite potholes of nostalgic territory. Hopefully their reflective indoor sounds will translate to a large summer festival stage. (Sunday, 12:00-12:30, PlayStation Stage) --text: Nick Meador
