Angle of Entry is a limited-issue live acoustic album recorded by the Mutton Birds during their 1997 Envy of Angels UK tour and released on their managers' label. It was sold at gigs and over the internet.
The album cover notes said the 12 Bar Club was "the sort of venue for which the word 'intimate' was invented. On a stage barely large enough to swing a cat, on stools perched precariously close to the side of the stage the Mutton Birds belted out a selection of their songs. It was one of those magical nights when the audience would call out the title of a song and the band would play it if it came up next on their set-list."
