At first, I had the same reaction; a lot of the progressions, melodies & even cadence of the vocals sounded reminiscent of "Wolfgang..", which is kinda funny in a way because there are always people who complain when bands change their sound -- and yet when it stays somewhat parallel in future releases the band typically gets criticized for being uninspired or whatever.
Personally, this record has grown on me with each spin. I loved their last album, so it's ironic that it ever felt negative for "Bankrupt!" to sound like it. There's enough musical/artistic progression there to certainly say that these songs are unique, while maintaining the catchy, spunky (did I just use that word? haha) tonality that I crave from this band.
The track "Chloroform" is currently my favorite.. the timing when the drums initially kick in is so awesome & sexy. I wouldn't say it's their best record by any means, but it's fresh and puts a smile on my face.. so what more could I really ask for?
I feel like there's a real deficit with bands that can pull this off lately -- you know, music that's pop/rock but not eye-gougingly repetitive like most of the top 40 stuff. I needed an album like this right now, and can't wait to hear the new Vampire Weekend/Daft Punk records as well. I listen to many different genres (pop/rock probably the least), but Phoenix is an undeniable force of fun. Definitely give "Bankrupt!" another chance if it didn't quite trim your hedges on your first listen.
