Es reiten die Toten so schnell... (German: The Dead ride so fast...) is the first demo tape by darkwave band Sopor Aeternus & the Ensemble of Shadows'. Es reiten... was issued in a hand-numbered limited edition of 50 copies in 1989. A further two demo tapes, Rufus and Till Time and Times Are Done, have not yet been released in any format. All three have been referred to as the "Undead-Trilogy".
