[SOLVED] Help with rarez (?) identification

[colorful人生 2777]

Hi, I was wondering if anyone was familiar with these particular CD/DVDs and could give me the artist and (mainly) titles in Romaji. 

I'm not familiar (or at least overly familiar to recognize the artist name) with these artists in terms of listening.

Brief history would be excellent!

 

These are the items without cases, I have a few other CD's that I plan on putting here (which will be in this particular post, I'm hoping this becomes a thread in the future where people can identify their stuff lol).

I'm not at all familiar with these artists, but...

 

The KISAKI one appears to be: "KISAKI - 「地下線神言基地」 購入者特典kisakiレアcd"

Romaji: KISAKI - 「Chikasen Shingon Kichi」 (Bonus kisaki rare cd)

 

The Magverry one is here: http://www.puresound.co.jp/script/detail.php?id=101082161001

this one doesn't have a "title" - it just says 無料配布CD Ver.2 ("Free distributed CD Ver.2")

 

The KING one has no title, so..
