Geoff Bartley (born 1948)[1] is an American acoustic guitarist and singer-songwriter based in Boston, Massachusetts.

[4] Among his influences, Bartley cites original pre-war acoustic blues players and singers such as Lightnin’ Hopkins, Robert Johnson, Bessie Smith, and Blind Willie McTell, as well as later musicians, such as Bob Dylan, Tom Rush, Bonnie Raitt, and Dave Van Ronk.

[7] In 1991, Bartley began hosting a folk singer-songwriter open mic at the Can Tab Lounge in Cambridge on Monday evenings.

The success of the folk open mic led the venue asked him in 1993 to host Tuesday evenings as well, and he decided to make that a bluegrass event.

[10] His recordings Put the Big Stone Down (2009) and Mercy for the Dispossessed (2011) both reached number one on the international Folk DJ Radio chart.
