Of both.
There's not much to say about the VU apart from that they were genuinely one of the greatest, most risk-taking bands in history. The major cliche "ahead of their time" is overused in connection with musical acts; here, it's actually valid. Bear in mind that this group's early beginnings were at roughly the same time as flower power and the summer of love. Talk about going out on a limb and against the commercial tide. No wonder their records sold badly at the time.
Songs - a quick and random list:
"Sister Ray"
"I Heard Her Call My Name"
"Jesus"
"I'm Set Free"
"Heroin"
"Candy Says"
"After Hours" (best song about death and coffins EVARRR :)
"Oh! Sweet Nuthin"
"The Black Angel's Death Song"
"Venus In Furs"
"Who Loves The Sun"
"Pale Blue Eyes" - (2 minutes too long, but still...)
"I Found A Reason"
"Here She Comes Now"
"Venus In Furs"
"European Son"
"She's My Best Friend"
"The Ocean"
"White Light / White Heat"
Lou Reed has the Dylan/Bowie syndrome - an artist whose work you value for what he did 20, 25 years ago, rather than anything recent. I think the guy misses Cale more than he would ever admit (although "Songs For Drella" wasn't stellar - OK, that rhyme was unintentional : )
Songs (best of the solo years. I actually have all his solo work, so in a way it's sad that this list is so short):
The "Transformer" album (not deep but it's fun)
"Street Hassle"
"Harry's Circumcision (Reverie Gone Astray)"
"Hello, It's Me" - (heartbreakingly sincere. This time I think he meant it.)
"The Kids" - (one of the most harrowing songs ever)
"Berlin"
"Coney Island Baby" - (sweet nostalgia. Is there a heart in the dude, somewhere?)
