For her husband, I like the later-period -- more abrasive, noisy stuff, 1965ish...
Get this one if you like Coltrane and don't have it. One of the best discs I bought in the 00s so far...
Fans of his earlier, more controlled performances generally shun this one as the recording quality stinks, but that's what helps make it so magical. It's very loud and throbbing and abrasive. Totally unrelenting and beautiful. Sublime even.
