Who: Boston band that lovingly pays homage to the big-hair metal they loved as kids with anthems built out of chugging riffs, wailing guitar solos and choruses (no verses!) sung by not one, not two, but upwards of 17 lead singers. Led by guitarists/indie-band vets Bryn Bennett and Alex Necochea, the band released its self-titled debut in February 2007. A for-fun throwaway song called "Bang Camaro" landed big on MySpace, and the rest is spandex-n-Aqua Net history. As Bennett puts it, "Just because you've started reading serious music criticism doesn't mean you can't love Def Leppard anymore."

Chorus Lines: Tracks like the Mötley Crüe-esque "Pleasure (Pleasure)" and cowbell-heavy "Out on the Streets" boast the kind of nudge-nudge-wink-wink wordplay that made The Darkness famous, but Bang Camaro also know the virtue of a great, simple lyric, like "Push Push (Lady Lightning)"'s "Ooh, come on / I want to take you higher / Ooh, come on / Let's make electric fire!"

Hear It Now: Fist-pump your way through single "Push Push (Lady Lightning)" from Bang Camaro, then catch the band on tour this summer.

Who Philadelphia quartet whose new album, You're My Lover Now, seems to channel The Kinks, The Who, and some burnout folkie we've never heard of -- all Brit-poppy harmonies, scrappy energy and weirdly endearing touches. The Teeth are fronted by twin brothers Peter and Aaron MoDavis, who formed The Teeth with two buddies after moving to Philly in 2001. "We were called the Pants," Aaron says. "We just wanted a name that didn't try to sound deep." The Teeth have persevered through shitty shows and some not-so-great jobs, including a pizza and cheesesteak joint where three members still work. Nowadays, though, things are looking up for The Teeth: Lover has gotten strong reviews, and The Teeth recently toured with their buddies (and RS fave) Dr. Dog. "It's going well," Aaron says. "People are coming to shows all over the country, and we're makin' cash - a little at least."

Brotherly Love As Lover shows, The Teeth are meticulous about crafting harmonies, melodies, chord changes and such. But sometimes their attention to detail leads to intra-band scrapes -- both onstage and off. "I gave Aaron shit about this one chord change," Peter Modavis says. "He flipped over a couch and I attacked him. We have a video where you can see his black eye."

Hear It Now Bite down hard on "The Ball of the Dead Rat," a hot track from You're My Lover Now.

Watch It Check out this clip The Teeth in both their acoustic and electric guises, playing "It's Not Funny" and "The Ball of the Dead Rat."

Last week, the White Stripes announced that Alabama-bred singer-songwriter Dan Sartain would be opening for them on much of their summer tour, prompting rock fans everywhere to wonder, "Who the fuck is Dan Sartain?" Well, we're here to help. Check out the dope video for Dan's single "Replacement Man," as well as this Rolling Stone "Breaking" profile, then plan to show up early for whatever Stripes show you're seeing this summer.

WHO: Exuberant English quartet with a lean, crude riff-rock sound and a brilliantly funny frontman, Eddie Argos, who specializes in childlike, half-spoken vocals about erectile dysfunction and other romantic misadventures. After declining to attend university - he deliberately flunked his admissions exams, choosing to write his essay about "the A-Team" - Argos formed Art Brut in 2002. After an endearingly funny 2005 debut and a series of killer live gigs on both sides of the Atlantic, Art Brut amped up their sound for their great new album, It's a Bit Complicated.

HEAR IT NOW: Complicated gets huge mileage out of a simple sound: Exuberant, garage-y banging overlayed with half-spoken jokes and narratives, with Argos picking through the ashtray of his brain and offering himself as the punchline - as on "Jealous Guy," where he tries to "accidentally" wake his sleeping girl to get laid. Check out that unique sound on Art Brut's MySpace page.

WATCH IT: Dig the video for Complicated's banging new single, "Direct Hit."
