John & Yoko / Plastic Ono Band with Elephant's Memory And Invisible Strings: Some Time in New York City (1972)

The review of this record on Allmusic highlights that site's schizophrenia. While awarding the record only 2.5 stars, the reviewer argues that the record "is some of the groovin'-est, most tuneful agit-prop ever committed to disc." Say what?

The record starts out with the controversial tune Woman is the Nigger of the World. I genuinely get what Lennon and Ono were trying to say, but not everyone was happy. Wikipedia notes:

The phrase "woman is the nigger of the world" was coined by Yoko Ono in an interview with Nova magazine in 1969 and was quoted on the magazine's cover. Literary analysts note that the phrase owes much to Zora Neale Hurston's novel, Their Eyes Were Watching God, in which the protagonist Janie Crawford says, "De nigger woman is de mule uh de world so fur as Ah can see." The song describes women's subservience to men and misogyny across all cultures.

In a 1972 interview on The Dick Cavett Show, John Lennon stated that Irish revolutionary James Connolly was an inspiration for the song. Lennon cited Connolly's statement "the female worker is the slave of the slave" in explaining the pro-feminist inspiration behind the song. [source]

Anyway, when the song comes on, it's difficult to know if I -- as a white person -- can sing along. I suppose that goes for a ton of rap tunes too. It also applies to Oliver's Army, that snappy Elvis Costello tune, when he sings:

"Only takes one itchy trigger
One more widow, one less white nigger"

So, I leave this argument to the academics. There are some great tunes on this record, and I do like the cover very much.
