A bit of a stab in the dark this one.

I have a sequence of late nights (working on computer) lined up and some good music will help.

I would be grateful for (youtubeable) links but if you don't mind they will have to be long players, blues based, no horns, hammond organ, gritty and no vocals.

Akin to the Boddingtons add

Many thanks

Blues based hardly narrows it down...;)

No vocals, no horns but possibly not gritty enough for you?

Here's 13.57 minutes to pass the time anyway...

Part 1:-
YouTube - Ronnie Earl & the Broadcasters - Part 1 "Rego Park Blues" (http://www.youtube.com/watch?v=YZpahrPqj34)

Search for the band of your choice and this will DJ for you:

Music Dewolfe Radio ? Last.fm (http://www.last.fm/listen/artist/Music%2BDewolfe/similarartists)

Or The Radio, which is currently rolling through Gordon Lightfoot songs for me as I Pprune.

theRADIO.com (http://www.theradio.com/)

I've actually lost the link but I think this is the one:
Radio llanera (http://radiollanera.com/)

Lots of vocals, but all in southeast-colombian spanish, so you can treat the vocal line just as another 'instrument'
