Watch out everyone, Green Day is back with “Warning,” perhaps the best album of their career.Billie Joe Armstrong, Tre Cool and Mike Dirnt produced this album themselves, thus allowing them more room for creativity.As producers, they had to pay attention to every little detail. This is the reason “Warning” is their most serious and best-written album to date.Green Day is known for being a goof-off band, so of course, not all their songs are going to be serious. With titles like “Blood, Sex and Booze” and “Fashion Victim,” it’s apparent Green Day are going to continue to keep their humorous side.The band’s last album, “Nimrod,” started their maturing process, but because the band only knows a few chords, obviously, their songs are going to sound very similar to each other. Fortunately, the band produced “Good Riddance (Time Of Your Life),” its break-out single. Besides being slow and toned down compared to their other songs, “Good Riddance” actually had a bit of meaning behind it.The latest album’s version of “Good Riddance,” would be either “Macy’s Day Parade,” or “Misery.” Both are slow, but “Misery” tells a story and seems to have a swing beat, while the hopeful “Macy’s Day Parade” is another sign of maturing by Green Day.Both these songs, along with the whole album, show how far Green Day has come from the days of “Dookie.” They are broadening their musical talent and writing songs with meaningful, and not just ludicrous, lyrics.Green Day also seems to take a political stand on this album. In songs like “Warning” and the first single, “Minority,” it might appear that the guys are becoming anti-government, following the steps of Rage Against the Machine or System of a Down. Keep in mind this is Green Day, though. Unlike the powerful and controversial lyrics of the other two bands, Green Day uses humor to get their point across.Green Day has always been ridiculed for not being a true punk band; they’ve even been called a pop band. Armstrong uses a fake British accent when he sings and they only know a few chords – but look how far knowing a few chords has taken the Offspring and Blink 182.The members of Green Day have always been known for being immature and insane just to get attention, but this album could change all that.Although it doesn’t seem like it, Green Day has been around for over a decade. “Warning” is bound to do for Green Day what “Dookie” did for them in 1994: Put them on the map as a great band. But at least now they deserve it.
