OK, I don't actually want to record penguins nor am I a penguin myself (at least not at this moment). I'm referring to Linux. Does anyone know of any good and easy-to-use recording software for Linux? I'm not interested in making albums on my computer or anything. I just want something that would allow me to record my guitar over one of the backing tracks posted here. I figure I'm at the point in my guitar skillz now where I can try this. I also would like a recorded history so I can see how I've progressed (or regressed as the case may be).
