After a six-year hiatus, the Beastie Boys return with To the Five Boroughs and position themselves alternately as pop-culture bottom feeders and political pedants. While anti-Bush screeds "That's It That's All" and "Time to Build" come across as heavy-handed, the terse "Open Letter to NYC" does manage to channel that city's post-9/11 resolve without sounding like a Bruce Springsteen song. When the Beasties aren't didactic, they're tapping nostalgia. The album's production has a bottom-heavy electro sheen that recalls early Eighties hip-hop; irreverent party-rocking jams such as "All Lifestyles," "Three the Hard Way," and "Ch-Check it Out" name-drop throwback icons Fred Sanford, Jabba the Hutt, and Mr. Furley. It's obviously nothing new for the Boys, and much of the album does reek of self-cannibalization, but Boroughs is comfort food for the die-hard fans -- and at this point that's all we can expect or even want.
