Flight feather

Flight feathers (Pennae volatus) are the long, stiff, asymmetrically shaped, but symmetrically paired pennaceous feathers on the wings or tail of a bird; those on the wings are called remiges (singular remex) while those on the tail are called rectrices (singular rectrix). The primary function of the flight feathers is to aid in the generation of both thrust and lift, thereby enabling flight. The flight feathers of some birds have evolved to perform additional functions, generally associated with territorial displays, courtship rituals or feeding methods. In some species, these feathers have developed into long showy plumes used in visual courtship displays, while in others they create a sound during display flights. Tiny serrations on the leading edge of their remiges help owls to fly silently (and therefore hunt more successfully), while the extra-stiff rectrices of woodpeckers help them to brace against tree trunks as they hammer. Even flightless birds still retain flight feathers, though sometimes in radically modified forms.

Broken (EP)

Broken is an EP released on September 22, 1992. American industrial rock band Nine Inch Nails' second extended release after Pretty Hate Machine, it consists entirely of new material and was their major label debut. Produced by frontman Trent Reznor and Flood, it replaces the electronica and synthpop style of Pretty Hate Machine with a considerably heavier sound that would act as a precursor for Nine Inch Nail's acclaimed second studio album, The Downward Spiral. Its influences are industrial metal and noise rock.

The music videos that accompanied 5 of the 8 total tracks were widely censored from television airplay due to their disturbing content. Nevertheless, "Wish" won the 1993 Grammy Award for Best Metal Performance as did "Happiness in Slavery" (live performance at Woodstock '94) in 1996. Contributing to the band's growing mainstream success, Broken debuted to generally positive reactions, and peaked at number 7 on the Billboard 200 chart. A companion remix EP, Fixed, was released in late 1992.
