I hope I got your question right as, unfortunately, I do not yet know any US American espresso blend

(At least I'm going to receive my first Canadian one soon and I can't wait to enjoy it!)
Throughout the last few years, in German supermarkets "100% Arabica" (and fair trade resp. organically grown beans) has become trendy.
Well known German roaster brands are Tchibo (which even carry a "private coffee" luxury line and have own shops, too), Jacobs, Darboven, Dallmayr, Melitta to name a few.
Sadly, most have undergone a quick industrial roasting process and do not originate from a drum roaster.
As to espresso, there's Illy (arabica), Lavazza (with robusta) and espresso blends by the a.m. German roasters (which are mostly "100% arabica").
Therefore, it's worth to go to one of the Italian supermarkets where many famous brands can be found (e.g. Kimbo, Segafredo, Casa Rinaldi, S-Caffè Schreyoegg, Ionia, Zicaffè) and further Italian varieties with an authentic (big) share of robusta, less famous but nontheless delicious and sometimes unfamiliar to our taste habits. For those outside bigger cities, online shops offering Italian or Swiss esrpesso blends are of helpful service. If you get a fresh bag, meaning it has been roasted 1 - 2 months before, you're lucky.
But if you're looking for really fresh roasted beans, you go to a local German roaster (most of them also have online shops). There are also some Italian roasters in Germany. These roasters offer specialty coffees, single origins, even cup of excellence beans, always high quality and long time roasted. Consequently, the coffee's more expensive (e.g. 20 Euro/kg vs. 12 Euro/kg - but the quality is so much superior you would have expected a much higher price...). Espresso gourmets preferably shop there or even roast themselves.
