“We’ve been making our own music since we were 13. It feels like it always did— arduous but necessary,” says Alex Frankel of the clubby-cool, electronic-based Holy Ghost! Clearly, this sense of necessity comes from a commitment to both passion and roots – both Frankel, and music soul mate/band mate/life mate, Nick Millhiser, have been in love with music, and New York, since, well, forever. So, how appropriate that the duo, along with their new live show band members, will be performing this Saturday at the chic music-praising, New York artists- embracing PS1. You should check it out – their seventies dance’y jams will be totally worth the heat (and wind…maybe rain… thanks Earl). And if their catchy sound isn’t convincing enough for you, or you’re too lazy to make that pretty effortless trek to Queens, remember that this will be the last PS1 Warm Up. I mean, how else were you planning on ending your summer with a hipster filled sonic boom? – Alex Daly

From the midnight show at Rockwood Music Hall to the lofts of good ole’ BK, the guys from Chappo have been stirring up the NYC indie music scene with good times, good vibes, and great sounds. The catastrophically crazy Southern duo, comprised of Alex Chappo and Chris Olson Chappo, have an energy that transcends from the stage to the streets, leaving a wake of “space dust” in their trail that keeps fans moving, shaking, and coming back for more. Often described as a huge party, Chappo shows set the bar regarding cosmic energy and out-of-body experiences, complete with props, noisemakers, and the occasional instrument. Their music is fearless, innovative and downright fun, infusing classic indie pop with complete chaos, achieving their goal of making the Chappo experience one meant to be out of this world. – Read Christina Morelli’s Q&A with the band here.

This Brooklyn three-piece, made up of Sam Sundoes, Davey Sarantos and Trevor Mcloughlin are creating lo-fi, catchy songs with creative melodies and straightforward vocals. With songs like “Keep it to Yourself,” The Sundelles bumbling, buzzing tunes create washed out blazes of sound with their fuzzy instrumentals while maintaining a clear melodic, bouncy tune with upbeat singing. Not the mention the group seems to have an affinity for young children, confetti, and balloons. In both music videos on their website, confetti is flying through the air, and in several photos and one video, there are adorable little children present. The Sundelles seem to be a band that likes to have a good time and show it through bright sounds, energetic drums and guitar, as well as their personality as a band. They seem like they have fun all the time, which is awesome. – Read Lauren Piper’s Q&A with the band here.

I love Apocalypse rap. I can’t get enough, really. It’s especially exciting to encounter an artist who is well-articulated, imaginative, and earnest while not coming off as superior and overly didactic. With a voice like a rabid pterodactyl, Propaganda Anonymous is raging against the machine. Listening to “Squat the Condos,” it is easy to imagine him dancing around the belly of the beast, feverishly flinging monkey wrenches into the metal guts. The polished electro-hop production pulses and swirls a monstrous and hypnotic backdrop for these stark revolutionary anthems. It’s a dark album, but not without some hopeful glimmerings. It shows you the burning city, but it also shows you that you’re the one holding the torch. – BrokeMC

Although New Jersey’s Big Troubles point to bands like Lilys, Swirlies and even pre-Loveless MBV as influences, one could make the case for them being the love child of The Pains of Being Pure at Heart. "Freudian Slips" has the bouncy happy hooks, head bobbing good vibe with just the right deviation into Reid Brothers sugary "Just Like Honey" smooth vocal textures. "Drastic and Difficult" amps up the sonics, as it all gets bigger and a bit noisier with more upfront and urgent vocals. The band’s dissonance kisses the edges of Sonic Youth’s abrasiveness, without completely teetering over the edge. "Bite Yr Tongue" drives home the truism that a great hooky guitar lick as the centerpiece of your song is always a win. It careens forward with Pains-like glee until the over-reverberated vocals and MBV style guitar fuzz makes sure there is no confusion with anything twee. "Modern Intimacy" is twisted surf pop that has Annette Funicello dancing with a Zombie, while "Former Selves" is the slow and lush sound providing the blueprint for the current wave of "new gaze" bands. Big Troubles will play as part of the upcoming CMJ showcase at Bruar Falls on October 19. – Dave Cromwell
