Jarrett is enormously & directly influential on most of the people playing today.
The first figure obvious greats like the late John Taylor, Marylin Crispell or Brad Mehldau get compared to is Jarrett.
Mehldau literally became Mehldau upon hearing Bremen/Lausanne.
What people call "the renaissance" of Crispell started with her working in his style with Peacock/Motian.
Second-tier figures like Craig Taborn, Vijay Iyer or Marc Copland exist in his shadow.
Literally the first thing you see when googling Svensson, THE pop star of jazz piano in the 00's is a Jarrett comparison.
It's the comparison with Coltrane that is off.
