I never clicked much with prog and Dream Theater were never my bag but I like the story you tell of your relationship with them. I've loved the shit out of a few bands but none over the course of their entire careers. In fact I can't think of a band who's released more than three albums in a row that I've been crazy about.
I did like Roxette though, and also wore out my Sony Walkman batteries at an alarming rate. As a kid I had a paper round and would play Joyride along with more manly fare like Slippery When Wet, Van Halen's first album, Hysteria, Bryan Adams' Reckless, the Top Gun soundtrack, the Days Of Thunder soundtrack and Thin Lizzy's Dedication. Then, when I was sixteen, Pearl Jam and Nirvana came along and rewired my brainbox and opened another world to me. I haven't listened to a Roxette album for almost couple of decades now, but whenever one of the songs comes on the radio or a vid on TV I'll still enjoy it. Those Swedes know their way around a pop song.
I've never been to a con. We don't have many out here in the South Pacific and every time one comes around I think I'll go check it out but then I remember how much I hate crowds. But I have drunk rum, and will continue to do so.
