Jonathan Feinberg
Jonathan "JD" Feinberg, nicknamed "The Doctor of Sound," was They Might Be Giants' first touring drummer (as confirmed by this answering machine message from John Flansburgh). He spent six months of 1992 on the Don't Tread On The Cut-Up Snake World Tour in support of Apollo 18, and performed "The Statue Got Me High" with the band on The Tonight Show. He recorded one song with the band at the time, "O Tannenbaum". In 2002, he provided percussion on "Now That You're One Of Us". He's also featured on the CD The Best Of Mountain Stage Live Volume Five, drumming on "Particle Man".
Flansburgh: "We've got a guy in the band whose name is remarkably close to mine. The drummer's name is Jon Feinberg. We actually call him J.D. Feinberg, just to avoid having another John." (The Baltimore Sun, September 18, 1992)
Feinberg worked as a programmer for Google for 13 years. Previously, while working for IBM Research, he developed Wordle, a tool that generates graphical "word clouds" (not to be confused with the 2021 word game).
