by Stephen Thomas ErlewineBush's grunge-by-the-numbers is certainly well produced. Under the guidance of Clive Langer and Alan Winstanley -- the kings of early-'80s British pop -- Bush turn in an album that follows all the rules and sounds of American hard rock, specifically Nirvana and Pearl Jam. Their songwriting isn't terribly original, nor is it particularly catchy. What makes "Everything Zen" and "Little Things" memorable is the exact reproduction of all of Nirvana's trademarks, only with a more professional execution. In other words, all the guitars keep rhythm perfectly and Gavin Rossdale doesn't shred his throat when he sings, he projects from his diaphragm. As far as pop craftmanship goes, it's actually quite impressive.
