The album IS more guitar driven, at least in comparison to Get Behind Me Satan, which was all over the place and not mainly guitar driven.
Anyways, i've been extremley, extremley pleased with Icky Thump. I've heard alot of people say that it's "just like their other albums" but honestly I find it pretty different. There's nothing quite like the pop of "You Don't Know What Love Is(You Just Do as You're Told)" on any other Stripes album, and certainly nothing quite as strange as "Prickly Thorn but Sweetly Worn" or the freak out that is "St. Andrew(The Battle is in the Air)". The cool little weird bits on "Little Cream Soda" are different too, and certainly whatever he's doing to his guitar on the title track isn't quite like anything he's done before.
My favorite tracks though are the ones that hark back to the sound of White Blood Cells like "Bone Broke", and "Rag & Bone". "Catch Hell Blues" reminds me alot of "Death Letter" from De Stigil and is probably my favorite overall track on the album, and "I'm Slowly Tuning Into You" reminds me alot of "There's No Home For You Here" in a good way.
Like I said, I really, really like the new album. It's certainly not the BEST White Stripes album, but it's definitley one of my new favorites of the year. Oh and just as a disclaimier, The White Stripes are in my top 5 favorite bands, so you should probably keep that in mind when thinking about my comments.
