The Poetry Show
Z is emphatically not a TV/video/computer user, but we make an exception as a very special occasional treat for the excellent HBO Family-produced Classical Baby series.
Happily, this series is not Baby Einstein-ish drivel (Mozart melodies played on a synthesizer, etc.), although the HBO website certainly pitches the classical-music-as-Ambien bit. The series itself, however, consists of imaginative excellently realized animated vignettes matched with real music, e.g. an excerpt from the Bartok Rumanian Dances featuring a violin-playing cricket perched atop his mushroom home, or Duke Ellington paired with a Fernand Leger painting, or a monkey band shimmying along with Perez Prado's Mambo No. 5. (OK, so it's not all classical...)
Even though Z is younger than the target age group, the new favorite is "The Poetry Show--I'm All Grown Up Now," co-produced with The Poetry Foundation. Though MMFCC objects heartily to the super-precocious and precious kidlet interviews that are interspersed with the "real" interviews, I'm a fan myself, and am especially fond of the very witty take on William Carlos Williams' This Is Just to Say. Alas, alack, the Williams clip is not available online. However, you'll get the idea from this clip of Gertrude Stein's A Very Valentine. Good times.
