[Q]: Question: What band(s) the artist whose song "Chamakay" Polachek contributed vocals belong to? Passage:In 2010, she joined Jorge Elbrecht of Brooklyn-based Violens to record a "sgin" of Justin Bieber's "Never Let You Go": "We went on YouTube to find a video among the highest ranks of hits, and came across 'Never Let You Go'. We went on to make what we call a 'sgin' (anagram of the word 'sing')—an original song written specifically to synch into someone else's video on mute". Caroline shot and directed video for Violens' "It Couldn't Be Perceived". Polachek and Elbrecht collaborated again in 2014 on two singles, "I.V. Aided Dreams (feat. Caroline Polachek)" and "Full Mental Erase (feat. Caroline Polachek)". In 2012, she sang with Ice Choir (solo project of Kurt Feldman of The Pains of Being Pure at Heart) on the song "Everything Is Spoilt by Use" and directed/edited its official video. Caroline contributed vocals to Blood Orange's "Chamakay" (2013), collaborating with Blood Orange again on "Holy Will" (2018). In late 2013, Polachek wrote and produced "No Angel", which was featured on Beyoncé's critically acclaimed fifth studio album, Beyoncé. Thanks to this song, at the 57th Annual Grammy Awards, she received a Grammy Award nomination for Album of the Year. Polachek then collaborated with PC Music's, Danny L Harle in early 2016 on the single "Ashes of Love". Polachek collaborated with felicita throughout his album "Hej!" (PC Music 2018) including an arrangement of the Polish traditional song "Byl Sobie Krol" (released under the title "Marzipan"), and with Charli XCX on Pop 2 (2017) on tracks "Tears (feat.

[Q]: Question: Of the grasses that the essex skipper eats, which is the longest? Passage:Eggs are laid in strings on the stems of grasses where they remain over the winter. The Essex skipper's favoured foodplant is cock's-foot (Dactylis glomerata), and it rarely uses the small skipper's favoured foodplant Yorkshire fog. Essex skippers' other foods include creeping soft grass (Holcus mollis), couch grass (Elymus repens), timothy-grass (Phleum pratense), meadow foxtail (Alopecurus pratensis), false brome (Brachypodium sylvaticum) and tor-grass (Brachypodium pinnatum). This skipper's caterpillars emerge in the spring and feed until June before forming shelters from leaves tied with silk at the base of the foodplant to pupate. Adults fly from July through August. Like most skippers, they are fairly strictly diurnal, though individuals are very rarely encountered during the night.
