It's a sine wave. From a waveform generator.
I enjoyed it - very old school and I love the lead sound.
The more minimal section in the middle is great in a Charlie Hall / Drum Club / Megadog stylee.
Ooh. Drum Club. They were a big influence.
Club Dog used to be my Friday night out, back in the day.
Never went to Club Dog but went to a fair few Megadogs in Leeds, Manchester and London.
You chose a suitably pagan-ish song title to go with that Psychick Warriors Ov Gaia groove too. Just realised how much the title suited the tune.
'Return to the source'
It's actually a play on the word 'sine'. I seem to be obsessed with them for some, strange, reason.
I did a set at a Megadog once. In the bar.
