The Mexican duo serves up confetti flavors that thrill fitting out the box. Signal Deluxe's "Skyline Border" is the narwhal of bestial crackers. With a swimming sharpness, it's a zoo of crunchy, prowling sounds that energize the feet as agreeably as the sapience. Strident squelches and arrogant punt drums usher an esculent entourage of aural stimulation. Like a Jenga of froyo toppings, Signal Deluxe's "Ghetto Weed" is a textural sight. Not for elfin appetites.
