David DiDonato (born October 27, 1973) is an American guitarist/composer/multi-instrumentalist/producer, best known for performing the World’s Longest Guitar Solo on May 13-14, 2012 and for being in a wide array of bands in Richmond, VA from 1992-2001 and Austin, Texas from 2001-present.

In 2006, DiDonato created a soundtrack to F.W. Murnau’s 1922 silent film Nosferatu, fusing classical guitar passages with instrumental black metal.

In early 2014, DiDonato began work on the soundtrack to Fritz Lang’s Metropolis. He is said to have spent roughly 2 hours on each 30-second long piece of the 2-hour and 28-minute long film. The soundtrack was finally completed in June of 2018, and has been performed in front of rapt audiences in Austin, Chicago, Dallas, Detroit, Florida, New York,  Olympia WA, Los Angeles, and Raleigh.

In early 2019, DiDonato began reworking his 2006 soundtrack to Murnau’s Nosferatu in anticipation of a Halloween release. This was performed a handful of times upon its completion, but future dates were cancelled due to the Coronavirus pandemic.

Over the course of the quarantine, he has performed at various drive-in theaters and spent the first 14 months of the lockdown scoring The Cabinet of Dr. Caligari. This was debuted in Detroit in late August of 2021.

In June of 2022, he began work on his fourth film, the 1921 Swedish documentary about witchcraft, Häxan. It was completed in October of 2023.
