Arthur Morgan "Arto" Lindsay (born May 28, 1953) is an American guitarist, singer, record producer and experimental composer.

He has a distinctive soft voice and an often noisy, self-taught guitar style consisting almost entirely of unconventional extended techniques, described by Brian Olewnick as "studiedly naïve ... sounding like the bastard child of Derek Bailey".

[6][7] "He's never lost his interest in weirdness," Robert Christgau wrote, "even ran the Kitchen for a year, and in the eighties his unschooled guitar was in demand all over downtown as he radiated out from the overlapping John Lurie, Anton Fier, John Zorn, and Kip Hanrahan circles to enterprising jazz and funk guys as well as Cuban drummers..."[8] After the Lounge Lizards, Lindsay and keyboardist Peter Scherer formed the Ambitious Lovers, influenced by pop, samba, and bossa nova.

He has produced recordings by Brazilian musicians Caetano Veloso, Tom Zé, Vinicius Cantuária, Gal Costa, Carlinhos Brown, Marisa Monte, Adriana Calcanhotto, Orquestra Contemporânea de Olinda and Lucas Santtana.
