I'd love to say it was Ceremony, but back then I was six years old and in Kindergarten, so I wasn't really all that developed, or empowered in terms of musical listening choices. It was essentially limited to whatever my brother and/or mom liked, some Queen here, some Abba there, and some Blondie and snuck in Go Go's material.
Oddly I have vague memories of hearing Love Will Tear Us Apart on the radio when I was five, whether that's an accurate memory or not is open to question. Anyway's the first New Order song I remember hearing is True Faith in 1987, but back then I wasn't open to it, neither was I too Blue Monday 1988, the next song I heard, which was good enough to make the cut on a mixed tape I made but go no further than that.
It was in '89 that a DJ in the bay area touted New Order on a radio tape I'd made for a trip, refering to an album as his all time favorite after the song had played (I'd gotten the chatter, but not the song), immediately following that I picked up Substance, thought it was interesting but still wasn't won over (I was bored by the versions of Confusion, and Thieves on it, Confusion would remain low, but Thieves would later become an all time favorite). The following winter I heard BLT in it's original form and was immediately won over, w/in a few months I'd buy half their albums, and the other half the following summer.
Now if only I could remember so well what my stupid user name and pass word were I wouldn't have had to set up a new account this past week. What an odd selective memory.
