Final answer:
Before the Beatles, singles were for hit songs to attract quick sales and radio play, while LPs allowed artists to explore diverse styles and concept albums that challenged conventional norms.
Step-by-step explanation:
Prior to the Beatles, singles and LPs had distinct functions and audiences in the music industry. Singles were for hit songs, aimed at being sold individually to target the charts and radio play.
Oftentimes, these were designed to be catchy and attracted the attention of a broad audience to generate quick sales.
In contrast, LPs (long-playing records) allowed artists to explore more diverse styles and concepts. LPs typically consisted of a collection of music, which gave artists more space to experiment and produce a full body of work that could include theme and narrative, rather than focusing on one or two hit singles.
This platform was particularly significant for the development of rock 'n' roll, which began to blend racial music barriers and allowed artists to challenge conventional norms, with the full-length album format providing them the creative space to do so.
