On both their earlier and later records, the Velvet Underground had incredible chemistry and ingenius songwriters. All of their songs had some interesting or special quality about them, even if they weren't always as forward-reaching as "Venus in Furs" or "Sister Ray". I definitely think Lou did his best work with them. On the other hand, I have a lot more trouble understanding solo Lou than I do understanding the Velvet Underground. An album like Berlin has lots of cool and thrilling moments, but I can only describe the actual songs as...well, unpleasant, if that makes sense. They aren't the kind of songs I can turn to in times of distress, the same way I can turn to the third Velvet Underground album. I feel the same even about Lou's more straightforwardly sentimental music. I can never tell what his angle is, so it can never mean the same.
