Well Broken Bells is actually a collaboration between James Mercer and Danger Mouse, so they don't have too much music out other then that one *Broken Bells* album and a EP. But if you like the vocals, then I recommend listening to Flake Music and The Shins. Flake Music pretty much what James Mercer was before he started The Shins, so they sound pretty similar, but I like Flake Music a bit more for some reason. Here is the entire Flake Music album *When You Land Here, It's Time to Return* which is really good. And then my favorite Shins song is Caring is Creepy. On the other hand, if you like the production of Broken Bells, then literally anything Danger Mouse produces is great. People who don't know who Danger Mouse is will be very surprised at how much influence he has had on popular works. But as for a recommendation, I'm not sure what I would suggest since Danger Mouse is kinda all over the place. I guess you could listen to my favorite album he produced which is *Demon Days* by Gorillaz, but that's not entirely him. Just go look at his wiki page and go from there since he has done so much haha.
