Toolless

Hi
There are 2 songs that I am looking for; I don't know the names or artists of the songs.
And it would be very difficult for me to describe to you as the songs have no lyrics.
That's right the songs I am talking about have no vocal artist so how am I supposed to describe it to you?

But they are 2 of the most populist club classic songs you will hear on the radio since the turn of the century.
In fact one of them was the theme music to a BBC2 program called something like the hustlers and the other song is very similar to this as the musical instruments seam to be the same .

Once again they are top club classic sellers of all recent times

So any ideas please
