and Sciences. No Hawaiian musician or group had been awarded a Grammy prior to the establishment of the Hawaiian Music category. One obstacle to the category's creation was defining Hawaiian music, and the eligibility requirements, in terms of music stylings and language restrictions. There has been conflict between traditional and Western-influenced Hawaiian music, mostly pertaining to the use of the slack-key guitar, an instrument invented in Hawaii but commercialized by "mainlanders". According to Academy representative Bill Freimuth, the category was designed "for recordings of a more traditional nature". Requiring the use of Hawaiian language on more than half of its vocal tracks encouraged the recognition of traditional music, but instrumental albums (such as the compilation album honored at the 47th Grammy Awards) circumvented this requirement. History Nominees for the 47th Grammy Awards (2005) included: The Brothers Cazimero for Some Call It Aloha... Don't Tell, producer Charles M. Brotman for Slack Key Guitar: Volume 2, Ho'okena for Cool Elevation, Amy Hānaialiʻi Gilliom, and arranger and multi-instrumentalist Willie K (born William Kahaialiʻi) for Amy & Willie Live, and Kealiʻi Reichel for Keʻalaokamaile. Hanaialiʻi and Reichel both expressed happiness at being nominated, the latter stating, "This is the culmination of the work of chanters, singers and poetry writers that dates back over a thousand years." One NPR contributor wrote that the nominees illustrated the range of Hawaiian music at the time, "from traditional songs for guitar and ukulele to more modernized approaches". Some Call It Aloha... Don't Tell contained traditional Hawaiian folk songs and chants and the use of traditional instruments such as the acoustic bass and 12-string guitar. Hoʻokena members Many Boyd, Horace K. Dudoit III, Chris Kamaka and Glen H.K. Smith created music for Cool Elevation using the ukulele, acoustic bass, and guitar. Scott Iwasaki of the Deseret News described Amy & Willie Live as a "playful array of Hawaiian jazz". Ke'alaokamaile, a concept album about Reichel's immediate ancestors, combines traditional Hawaiian chants with original songs. The album also included contemporary covers of Babyface's "You Were There", Karla Bonoff's "Goodbye My Friend", and Sting's "Fields of Gold". The award went to Brotman for the slack key guitar compilation album recorded in Hawaii and described by journalist Nate Chinen as "an easy-listening instrumental compilation seemingly tailored to mainland tastes". According to Jon de Mello, founder of Hawaiian record label Mountain Apple Company, other nominees' "jaws dropped on the ground" at the ceremony
