What Rentals stuff have you heard? I have all three of their albums, and their Songs about Time series of EPs. Their first album was great, but their newsest one, Lost in Alphaville, is my favorite. The Songs About Time series wasn't bad, but it's mostly demo-level recording quality, and almost every song on Lost in Alphaville was a reworking and improvement over songs that were on it.
Their second album, although I like almost every song individually, doesn't really flow well as an album, and rarely sounds specifically Rentals-y. They branched out into a lot of different styles and got a decent amount of guest musicians and vocalists, so it winds up sounding almost more like a mixtape than an album by a single band.
