Aftertaste is my 4th favorite. Betty, Meantime, Size Matters, Aftertaste, Monochrome, Strap it On. I get in Aftertaste moods though, for sure. I'm not a fan of Page's singing style on Aftertaste, its real goofy. Like if I didn't already know what he looked like, I'd expect a Sesame Street character with just a slit for a mouth that can't make an "O" shape. Some of the songs are too slow for my tastes too. Songs like Easy to Get Bored and Like I Care sound too slow, laborious, and lunkheaded. My favorites include Pure, Insatiable, Renovation, Birth Defect, and (High) Visibility.
I think I got it third (Meantime 1st, then Betty) on eBay which I guess tells you how long I've been a fan. My guess would be summer 03? I was rediscovering my love of grunge and Helmet was listed as a similar artist to Tad on allmusic.com. So I gave a few songs a listen and that was the end of it pretty much.
So Aftertaste is ok for helmet and good by anyone else's standards. It doesn't really hold any special place in my heart and I don't have a cute little story that involves Aftertaste, but every now and again...I rock it out.
