Hmm, saying three instruments can be looked at two different ways. If you do something like metal then these instruments are literal. Bass, a lead and a backing. If you're someone like me who owns some hardware synths then each instrument can have an infinite number of different tones that can then be multi-trakced ontop of each other. I could only use one synth for the entire song but acheive a completed mix.

With that aside, here is a song I uploaded a few days ago. It only uses two instruments (but they have been recorded then dubbed in a multi-track sequencer). The instruments are a Casio VL-1 (synth and drums) and a Vocoder.

Any good? :)

Wow! That's utter wank! It's forcing the stereotypical style of "men have short hair" on you. You should've kept your hair long then said this... "Jesus had long hair". That would've shut the tw*ts up! Especially if they were religiouse! lol XD
My hair is halfway down my back when it's been straightened (but I usually just have it in a male-tail), people tell me to cut it all the time! I just give them the finger and get on with my life.
In college they objected to me wearing a collar and some of my... how should I put it... 'more flamboiant gothic attire'. Like my fishnet tops and the nail-polish, lol! XD But I simply said "we don't have a uniform or any regulations relating to a uniform look". They retreated. You should've quoted human rights or something. But not to worry, your hair will grow back eventually, just hide it under a bandanna if those are permitted. My friend has these tablets that make your hair grow really fast like a garden weed! In the morning in I'll give him a bell and ask them what they are called if you want. :)
