I have been unearthing some stuff I recorded years ago.

This one has a catchy riff I came up with. I just had the riff and then I would come up with an entire "song", so, in other words, I'd improvise around the riff and come up with other riffs as I improvise. It's cool to do that and to slowly build up the anticipation and then hit it off with that riff! And then modify it, and have lots of fun! I miss the good ole days when I could plug my guitar into an amp. Now it's f**ked and no sound comes out of the amp. It's the guitar's fault, not the amp's cuz some little cable inside the guitar broke IIRC. I might actually buy a new electric guitar. And use the old one acoustically like I've been for the past 3 years or so.

Another thing I liked to do with an amp was to play a simple backing track and then improvise over it. Most of the time, I'd just mindlessly play a scale over these bass notes, but sometimes something interesting came out of that. In this one, I'm trying to play psychedelic/noise rock without any pedals. But I have some more of these like this one:

This one has me playing something like a triumphant black metal (lol) AND singing over it. This is a pretty cool way to come up with melodies as you play. You don't really need to know how to sing. You just sing, record it, and later you can replace your singing with a keyboard melody or something. It's never been about technical perfection with these recordings, but rather about either saving an idea or recording some improvisation, then listening to it back and picking up some interesting parts. Or just forgetting it for years and unearthing it now.

And here's my attempt at making the trvest black metal ever!!!

And here's "Voracious Aberration - Attacking the Virgin From Behind". I really loved to come up with a band & song name every time I came up with a new song idea. Another title of a br00tal song I composed was "Broken Limbs of a Virgin - Trepidation of F***slut's Skull"

Without an amp, I turned into a guitarist of the 'playing chords and singing' type. To my neighbor's distress.
My mom loved hearing me do that, so I'd do it with many different songs just for her. I'm a bad singer, but I enjoy singing!

Well, one way to come up with lyrics is just to sing some gibberish over the chords and see what sticks. Sometimes, however, your improvised lyrics are not what you expected... Well, this might be the most genius piece of lyrics I ever composed, though!
