Here's a quote from the above link;
"It is not too much to say that the present revival of interest in the Chorale Prelude in England is largely due to the impression made on English organists by his 'Sixty-six Chorale Improvisations,' Op 65 which appeared in 1909. They show a variety of treatment, an intimacy of expression, and a wealth of harmonic and contrapuntal resource that make the collection the nearest approach, and a worthy successor, to J.S. Bach's labours in the same field. There appears to be no method of treatment used by Bach that Karg-Elert does not also employ, plus some devices of his own, e.g. an ingenious use of dance measures as rhythmical bases. But whatever the chosen form may be, the music is intensely alive and expressive."
His favourite instrument to compose for was the Kunstharmonium. To hear Karg-Elert's creativity and the flexibility and range of colours offered by the Kunstharmonium go here'
