Just to give a quick background of where we found this latest piece: ‘Escape-from-a-room‘-style flash games have been very popular in recent years, and the most recent release that I tried is by Afro-Ninja, called Phone Booth.
Aside from the fact that it is again one of the most fun (and quick) escape games that I’ve played, the ending Afro-Ninja theme really had me hooked, so I immediately clicked on the link to KTRecords.
KTRecords are Kelwynshade (Josh Kemp) and Ncjason77 (Jason Turner) , who have ‘combined their music talents to form KTRecords‘. They have uploaded around 4 releases/draft versions of their work so far, and my favourite is definitely KTR hip hoppin.
The song has a fantastic tune running through it, with a strong rhythm underlying the entire piece, which may seem repetitive for some, but for me there are enough extra effects and variations to like this a lot. The duo are actually looking for lyrics to this short piece, so if you fancy a go, please do get in touch with them!
As with Esnips, you can listen to music without registering at Newgrounds, and so if you have 2:30 minutes spare, I would strongly encourage you to listen to it! 
If you prefer less hiphop-modern style songs, KTRecords have also written other short pieces, such as Starting Over, Piano Acoustic and Deeper than Deep which are all mellower than KTR hop hippin and are equally chilled out.
Jason from KTR here! Just wanted to thank you for the sweet write up on us! Always good to know someone out there enjoys our music (lol). We’ve had a few new songs since this was posted so you might want to check them out. Including the finished Afro Ninja Theme song. Also… check out Josh’s solo work. If you think our stuff is good when we’re working together, then his stuff will just blow you away. That’s all I got for now. Drop us a line if you’re ever on newgrounds again. Talk to you you later!
