10 buck drum machine and some Shiraz
I play the guitar. Mostly mellow stuff: Wilco, Willie, R.E.M. and the occasional try at Journey. But tonight, I was a one-man band with my new mini-keyboard. I turned "You Were Always On My Mind" into a pretty sweet hip-hop tune. I played the first song I learned on the guitar (R.E.M.'s Country Feedback - check out the audio sample) against a samba beat.
Best $10 I've spent in a long, long time.
