"Nothing if not epic, the band's buzzing guitar and screeching synth drew a massive and enthusiastic crowd of curious fans into the shade of the Troo Music Lounge, which eventually overflowed into the grass, forcing latecomers to peek over shoulders and peer through cracks in the tent for a glimpse of the sweat soaked trio gyrating onstage. As the set finally drew to a close, there was a palpable sense of excitement for what the rest of the weekend had in store."

From Wikipedia:
The Big Sleep are a three piece band based in Brooklyn, New York. They are signed to French Kiss Records. Formed in 2003, the band's discography includes the self-released EP -- You Today, Me Tomorrow and the full-length Son Of The Tiger LP (released in late 2006). Having drawn comparisons to fellow New Yorkers Sonic Youth, The Big Sleep's sound deviates from that of more recently formed contemporaries. Often without vocals, The Big Sleep's songs are for the most part instrumentals leaning towards post-rock or shoegaze, however often with a psychedelic feel hearkening back to classic rock such as Led Zeppelin or Black Sabbath.

"Barria's slashed and torn tone carried across the field, pushing a blast of dark reverb and tough fuzz and touches of dream-pop swirl that spread the notes out like melting glass, but lost no touch of intensity. He has a real-deal, singular tone, something you don't hear so much these days. Jimmy Page built a singular tone, Angus Young did too. And it's a bigger thing than picking good pedals and amps; it's the mark of a craftsman."

"One of my favorite parts of Bonnaroo: not giving a hoot about whether they look hip or not, fans are cheerfully dancing to any music they like. People were pogo-ing to the math-rock of the Big Sleep, a Brooklyn band that takes tangents into visceral punk and metal before unveiling new patterns."
