"Rosetta Stoned" is a song by American rock band Tool. It was released on April 28, 2006, as the eighth track off their fourth studio album, 10,000 Days.
The preceding track on the album, "Lost Keys (Blame Hofmann)" serves as a conceptually synchronized prologue for the song. It depicts a conversation between a patient (Albert Hofmann), a nurse and a doctor (R. Gordon Wasson), which occurs after the event in "Rosetta Stoned".[6]
The song generally received positive reviews from critics. It was also praised for its arranging and performances,[3] especially due to Danny Carey's "multi-limbed" percussion skills and creative drumming.[1][7] Critics also likened the song to The Grateful Dead's works.[3] The similarities between this song and another Tool song, "Third Eye," also have been noted.[4] Nick Cowen from Drowned in Sound gave a positive review to the song, appreciating its narration, intense mood, and guitar work.[6] The song was also musically compared to an extensive jam.[7]
