RHCP released a new album (or are about to) and I've been hearing good things about it.
If you're already a fan of RHCPs, you'll probably like it. There are a few good tracks, but as a start to finish album I don't think it is that remarkable.
The change in production from Rick Rubin to Danger Mouse was a great choice. Especially when compared to their past releases, this is a great sounding album. It also is a bit more textured instrumentally than past Chili Peppers releases.
Blood Sugar Sex Magik was a great sounding album, but otherwise, Rubin has ruined every Red Hot Chili Peppers album he has produced with the notoriously awful brickwalled mix. (AKA everything is made to be as loud as possible so there is no actual dynamic between the instruments). Granted, this is great for selling records as it makes singles stand out on bad car FM radios and low end computer speakers so I guess he did his job well, but if you actually want to listen to the album it makes it sounds lifeless and makes the process of listening to it unbearable and exhausting.
If you have liked the Chili Peppers in the past, it is worth a listen. If a huge Chili Peppers fan says they really enjoy the album, I wouldn't bat an eye, but for me it is probably not an album that I'd find myself revisiting again and again for years.
edit: apparently the CD version is still brickwalled.
