I just stumbled across the "Linux Rock Star" blog, which covers Linux audio applications, hardware, synths, etc.
If you're into audio/music production and run Linux, this site will most definitely come in handy.
There are many music apps available for Linux including Synthesizers, DAW's (Digital Audio Workstations), Trackers, Sequencers and much more. There are also complete Linux Distributions available with all of the programs setup and ready to use. My goal is to cover many of these available programs and make them accessible to the reader.
Sounds like a niche that could use filling! Check it out and be sure to add this one to your feed reader.
