Laine's Reliance Brass Band was the first to fuse European, African, and Latin music.

The earliest jazz musicians can be traced back to playing in the Reliance Brass Band or being influenced by those who had.

[5] Due to the diverse background of many of his band's members, a broad range of ideas developed and fused, leading to the early beginnings of jazz music.

Therefore, his band attracted a large and diverse group of people such as Mexican clarinetist Lorenzo Tio, Sr., a pioneer of the jazz solo.

[5] Laine retired from the music booking business by 1920, but he was interviewed a number of times, providing first-hand accounts of the early days of the development of New Orleans jazz.
