K-Solo (born Kevin Madison on April 17, 1967) is an American rapper
from Central Islip, New York who, along with EPMD, Redman, Das
EFX, and Keith Murray, was part of the Hit Squad in 1990s.
His two biggest hits were "Your Mom's in My Business" and "Spellbound." The
rapper later accused DMX of stealing this style from him when the
two were serving jail time together. 
In the mid-90s he signed with Death Row Records after hooking up
with them in a Pittsburgh show. The only track ever released was
a bootleg of Kurupt and him freestyling over "Gin and Juice".
It can be found on youtube. In 2003 he toured the world with PMD
and DJ Honda and vowed never again citing PMD "flipping over
nearly everything but his ticket and record sales."
In 2004 he was working on a new album for his Waste Management Records
tentatively titled "There Will Be Hell to Pay" which has
yet to be released.
During the mid 1990s through the early 2000s, DMX and K-Solo, who
first met as inmates in prison during the course of K-Solo's three
year prison stint, disputed over who was the first to write "Spellbound".
Despite that K-Solo released his version in 1990, DMX, who released
his version in 1994, claimed that he was the first to write "Spellbound".
In his 1998 hit single "Get At Me Dog", DMX told K-Solo
to "suck [his] dick". On Beef II, K-Solo took a lie detector
test to prove that he was the first to write "Spellbound".
The results were inconclusive.
In an August 2006 interview with  he had this to say:
"The truth of the matter is that being in L.A., I have people
that I never would in LA, like Tito Ortiz, Chuck Lidell, true beat-that-ass-niggas.
I have personally talked to the UFC folks and they would love to
see us fight, I would love to see us fight. I mean we are forever
going to be linked in the beef shit because there has not been a
clear winner. I feel that I destroyed him, I assume he feels the
same. It’s obvious we both don’t like each other and
I think it’s the only why too settle this beef, but let’s
face it, I saw dude do 50 push-ups and almost fall down afterwards.
It took like 10 minutes to catch his breath to smoke another cigarette;
obviously he is not ready for that. It would be the biggest deal
in hip-hop in 20 years."
In a Jan 2007 interview with  was asked why DMX has continued
to fan the flames such as his recent appearance on Hot 97 and stated:
"He knows what it is. I told him to get into the cage with
me. Five rounds, homie, fight me! He wouldn’t do it. I am asking
Keith Murray to do the same. I’ll break his ass down in two.
He’s a five dollar dude. Sign the papers, we’ll set it
up, and can handle it. That goes for any ma’fucka who has problems
with me. We’ll get in the cage. If you can beat me, you get
the money and I’ll get my ass beat. Let people do what they
got to do. I’m in war mode. I’m more ready now than I’ve
ever been. People aren’t getting away with that dumb shit.
DMX can’t fight."
 Keith Murray
In a Jan 2007 interview  responded to claims that he [Keith]
knocked him out:
"I was in the hood watching these guys. I ran with one of these
guys who was in the hood. A while back, my boy – Ralph Mann
got jumped by a few of the L.O.D. cats [Keith Murray’s crew].
They were disrespecting Ralph! I put Murray and Redman in the game!
So, I put they asses on blast on a mixtape! Murray’s men jumped
me on stage and threw me off the bitch. They’re now in court
because of the shit. But let me ask you -- how do I get jumped in
your club on Christmas Eve and walk out still alright? I could’ve
respected it if Murray ran up on me and did his thing. But he didn’t.
He thinks that the world is against him. If there was no Kevin Madison
there wouldn’t be no Keith Murray, because no one would’ve
respected him. Why fight someone that put you on? The only thing
that I can think is that Reggie and Erick put him on to doing it.
These cats are crazy, though. People were hurt when the Hit Squad
broke up. I know people who can call on J. Prince and really cause
some problems. Cats are just stupid. That’s the only thing
that aggravates me. What else do I have to do to show people that
I’m the “original rap criminal”? People don’t
know what they’re playing with."
