Thompson, performing with his band, was recorded at The Bayou, a music venue in Washington, D.C. As the album's title suggests, Henry Kaiser's track selection for More Guitar places emphasis on Thompson's electric guitar soloing – though it stands by itself as a complete performance, and accordion player John Kirkpatrick is given an extended solo on The Animals hit "We Got To Get Out Of This Place".

Thompson's playing on this album is technically impressive and fluent (even by the standards of a man long hailed as one of rock music's most talented and novel players), harmonically sophisticated and shows his wide stylistic range and influences – from British folk forms on "The Angels Took My Racehorse Away" to bebop on the opening "Don't Tempt Me".

Mattacks was unable to play the gigs due to injury, according to a review of the show published by The Washington Post.

Though the liner notes for More Guitar do not provide the exact date of the recording or any engineering credits, the Watching the Dark compilation does provide this information for two tracks included on the compilation that were recorded during the performance featured on More Guitar.

A contemporaneous newspaper review of the show, published on November 9 in The Washington Post, confirms the date of the performance.
