After mentioning 4mat, one of my favorite chiptune musicians, I thought I’d note a few others that I’ve come across in recent years.
For some time, this album was available only on CD-R, directly from the artist. (I have a copy, its title hand-written in permanent marker.) But you can now download the album here for free.
Tugboat announced in 2008 that he wasn’t creating this type of music anymore, and I haven’t come across anything else by him, but I think this album is excellent.
And you can find more of his music here.
This one isn’t by a single composer–it’s a compilation of 50 songs by many different artists. I think it’s available only on CD and not as a download.
I have the CD set and I highly recommend it, but if you’re just looking for free music you can download the 20-track “bonus disc” here. These are songs that didn’t make the 2 CD set, but I found them to be just as good as the ones that were included.
I could list many more, but I suppose this is enough for one post.
