Transit Records – Label Recording Music Production

I have been playing the guitar for over a year now, by using chords from the websites and stuff. But I think it would do me good if I learned a bit of music theory and could read sheet music. The problem is that the only time I am free is past midnight and I don’t think I’d be able to take any classes for this.

So, does anyone know of any site or any book which can help me out a bit here? Thanks in advance.
