Far too many through the years that have blown me away, like my 1st real fav, has to be hearing The Bassheads - Is there anybody out there in a club, but then heard ASHA - JJ Tribute, which also blew me away. Then heard Jimi Polo - Better Days (in the Hac) blew me away again. far too hard to make a choice, others I could mention too, like Techno Age - Movin' on, K-Klass - Rhythym is a mystery, Annie Lennox - Little Bird, Sweet Mercy - Take me away, I could go on all day, just depended on where I was when I first heard the tunes and what state I was in at the time they were 'dropped', but all those tunes mentioned and more had an impact straight away, all of them instant, no 'growers' in there.
