Every week, Hype Monitor wades through the most buzzed-about bands all across the Internet.

The Band: Passion Pit
The Buzz: Squirrely electropop where speedy beats carry high, girlish vocals across bands of synthesizer.
Listen If: You wonder what Built to Spill might sound like if someone stole all of Doug Martsch's guitars.
Key Track: "Cuddle Fuddle," which uses a plinking piano loop to singlehandedly invent 25th century ragtime.

The Band: FM Belfast
The Buzz: It's electric! Stern, keyboard-driven robopop — the sound of a zillion traffic lights blinking above empty streets.
Listen If: You find the Knife a bit too cheerful, or think big beats are better for brooding than grooving.
Key Track: "Lotus," which flash-freezes Rage Against the Machine's "Killing in the Name" in shivery synths.

The Band: The High Wire
The Buzz: Spacious, somber indie rock that shrouds broad guitar strumming and long, languid keyboard lines in warm, gentle mist.
Listen If: You always liked Slowdive a little more than My Bloody Valentine.
Key Track: "Saint Bees," where a curlicue melodica turns tricks over whispery vocals.
