20 years ago today (4/28/06), Tool released their fourth album 10,000 Days. Arriving five years after Lateralus, 10,000 Days doubles down on atmosphere, restraint, and emotional weight. At its core is the two-part suite “Wings for Marie (Pt. 1)” and “10,000 Days (Wings Pt. 2),” a deeply personal tribute to Maynard James Keenan’s mother, who lived paralyzed for nearly 27 years. It stands as one of the most affecting pieces in Tool’s catalog.
