Florida has been a breeding ground for some awesome bands as of late. Sleep Patterns is no exception. Hailing from Boca Raton, they play a frantic and intense style of hardcore. Their debut EP is self-titled and has been out for a little over a year, but the band will be releasing new material courtesy of 13th Floor records in the near future.

You can cut the tension with a knife with the siren-wailing feedback in the intro of "Green Glass Door." This is a precursor to what you're in store for in the rest of this EP. The vein-popping, throat-shredding vocals come in and are the perfect fit for this chaotic and angst-ridden band. They drive in the 'money riff' if you will, except in this case it's an extremely dissonant chord progression. However, they go back and forth between that and some other progressions with start-and-stop passages and vary up the dynamics in the middle. That doesn't last for very long, as the pinnacle of the song breaks in with the lines "Well please let it be known that I'm a walking example of what you shouldn't be/
And I will not change for anyone, or anything."

My favorite track on this EP is the second track, "Avon Park." The feedback from the previous song creeps in here as there's no room to breathe between tracks. Lyrically, this seems to be about someone with an alcohol addiction: "But if we're being honest/Wouldn't trust a word you say/You're stuck inside the bottle." Possibly my favorite small subtlety or nuance of the record is when everything cuts out but the vocals. The vocals sound far away when he screams "So save your" and then "breath" comes so in-your-face with the full band, it gives me chills when I listen to it. We see the more emotional side of the band too about 3/4ths through the song. There's some ambient guitar work and a wash of cymbals before going right back into a groovy outro.

"361TUF" sees a bit of a different direction for the band. It's the longest cut at 3:00, and is a bit more melodic and catchy to those who may not be too fond of dissonance. The chorus (I believe it's the chorus at least) riff/chord progression was one of the most memorable guitar moments on here for me. This track lyrically expands upon the emotional side of the band: "Why can't you see? Your mother cries/ Why can't you see ?My father's dead inside."

"Catfish" may be the most intense we see the band on the record. It's full of fast, downtuned, mathy riffage, dissonant chord progressions. The furiously accurate drumming/booming bass accompaniment help keep the band tight. Not to mention the incredibly caustic vocals and haunting lyrics soaring over everything. I have to say though, I was really not a fan of the guest vocal spot at the end. That's really the only negative thing I can say about this EP though.

Last up is "Slapshot Regatta." The riffs on this track remind me of one of Every Time I Die's more intense songs. You get the impression that the band is giving everything they've got left and pouring it into this song. They combine everything you've liked the band and give it one last shot. The last line is belted out "I've seen the tallest of giants fall to their knees," and then it brings us right back where we started with wailing feedback.

The recording quality on this is really good too. I love the guitar and bass tones, the drums sound great, and so do the vocals. Everything is well-mixed too-I can hear each part clearly throughout.

If you're a fan of intense, dark, visceral, in-your-face hardcore, there's no excuse not to check this out. It's up for free download on bandcamp, make sure to give it a listen.
