The Beatles had a diverse career and transitioned through several distinctive eras. Apart from the Psychedelic and Beatlemania eras you mentioned, there are two other significant periods in their musical journey:

1. The Early Years or Pre-Fame Era: This era spans from the Beatles' formation in 1960 in Liverpool, England up until their breakthrough in 1963. During this time, they were primarily known for their energetic performances in clubs and small venues. Notable songs from this era include "Love Me Do," "I Saw Her Standing There," and "Please Please Me."

2. The Post-Beatlemania Era or the Experimental/Studio Years: This era commenced around 1966 after the Beatles stopped touring and focused more on studio work. The band began exploring a broader range of musical styles, incorporating experimental elements, and introduced innovative recording techniques. This period is marked by albums like "Revolver," "Sgt. Pepper's Lonely Hearts Club Band," and the White Album, which showcased their evolving musical genius.
