@boxer12, Just listened to The Trinity Session and I like it okay. Sweet Jane, Blue Moon Revisited and Misguided Angel are particularly good. Many of these songs are covers and they do a good job but they're own stuff on Lay It Down is really good.
One article I read says that Lay It Down is their first album where they are pretty much fully rock rather than alt country. Lay It Down has an alt country vibe so I'm not sure I agree.
Anyway, give Lay It Down a listen. So far, to me, its their best work.
