According to Wikipedia, Channel Z-95.7 debuted as a Modern AC in January 1997. At some point in 1998, the station evolved to the first of many variations of Mainstream CHR. It seems that this aircheck was recorded in the middle of that transition – the “Groove Nation” mixshow seems to have been produced for Modern AC outlets, yet Channel Z-95.7 aired a listener’s phone call requesting “Too Close” by Next, which was more appropriate for a CHR station.
