This looks to me like a customized version of Trade Gothic, News Gothic, Benton Sans, Franklin Gothic, etc. But if you're looking for a face that has some of the distinctive characters already included...

Akkurat has the curved l but not the one-story g.

Flama has the curved l and one-story g, but DIN-like construction.

Foco has the desired features but adds a hint of calligraphic construction.

side note:
maybe you already knew this, but they are custom letterforms.

there is a nice story about it here:

I can get your single-storey 'g' and tailed 'l', but not the double 'a':
