One indication of slack key's increasing visibility beyond the Islands is that the first four winners of the Grammy Award for Best Hawaiian Music Album were slack key collections: "Slack Key Guitar, Volume 2" in 2005, "Masters of Hawaiian Slack Key Guitar, Volume 1" in 2006, "Legends of Hawaiian Slack Key Guitar—Live from Maui" and "Treasures of Hawaiian Slack Key Guitar – Live in Concert from Maui." Players from outside Hawaii have also taken up the tradition, for example, Chet Atkins (who included slack key pieces on two of his albums), Yuki Yamauchi (a student of Raymond Kāne's and an advocate of Hawaiian music in Japan), pianist George Winston, and Canadian Jim "Kimo" West (perhaps better known as guitarist with "Weird Al" Yankovic).
