One more essential album: "A Child's Garden of Grass: A Pre-Legalization Comedy." Back in 1971 when this album was released, who could dream that someday we would hear this question at our local over-the-counter store: "Fliptop, flat box, soft pack, or bulk?" From one of the many funny sketches that permeate this gem that flew under the radar for decades.... Check it out on YouTube.

There are some stellar albums on this list.

I would add:
DJ Shadow – Preemptive Strike
Ween – The Mollusk
Johnny Cash – American Recordings
Novadriver – Void

NICE shoutout to Dukes of Stratosphear! All Funkadelic is good, not just Maggot Brain. One Nation Under a Groove is important. You're missing out if you haven't heard Tipper's Broken Soul Jamboree.
