Billed as Kammerer & Howland, the duo described themselves as a "Classical Comedy Singing and Talking Act", and as performers of "Jollity and Jingles Mirthfully Mingled".

[3] During her years as a pupil of the Fischers, Howland frequently performed classical piano music for public audiences.

In 1907, Howland headlined a benefit for the Women's Christian Temperance Union at Frances Willard Hall on Snow Street.

[4] A year later she joined Providence Mayor Patrick J. McCarthy to entertain members of the Rhode Island Pharmaceutical Association at their annual conference.

[5] In June 1909, Howland began making weekly appearances as a performer of illustrated songs at the Bijou theatre, one of Providence's many vaudeville houses.

They were known for comedic songs, clever banter, acrobatic dancing, and for Kammerer’s impersonations of Ford Sterling, Charlie Chaplin, and Bert Williams.

[12] Billboard’s burlesque critic wrote: “Edna Howland as an ingenue appears to good advantage by interspersing some real comedy into her actions, singing and dancing, all of which she does well.”[13] While on tour with Pat White's Gaiety Girls, Howland gave birth to her only child, Donald L. Kammerer, born on May 28, 1920, in St. Louis, Missouri.

Howland returned to Providence, Rhode Island with their son and proceeded to sue Kammerer for divorce on grounds of neglect and extreme cruelty.
