It was recorded between June 1967 (Burning Of The Midnight Lamp) and June 1968.

Released October 1968- by this time, as Electric Ladyland was becoming Number One in America, the Jimi Hendrix Experience broke up- or rather, fell apart.

Chas Chandler produced Crosstown Traffic, Burning of the Midnight Lamp and All Along the Watchtower. He left during the recording of Gypsy Eyes, a song of which Hendrix eventually recorded some fifty takes. 

Jimi Hendrix's underwater opus on Side Three[?], is comprised of- Rainy Day, Dream Away/1983... a merman I should turn to be/Moon, turn the tides... gently gently away/Still Raining, Still Dreaming. For just under twenty-three minutes, Hendrix guides the listener on an undersea trek that is one of the greatest examples of psychedelia ever recorded. It truly rivals the Beatles' Sgt. Pepper's Lonely Heart's Club in terms of sheer ambition. In musical scope, it exists in the same realm as Miles Davis' Bitches Brew. 

For the making of Electric Ladyland, Hendrix brought along many friends and passengers. Jack Casady of Jefferson Airplane played bass on Voodoo Chile. No less than three members of Traffic made contributions- Chris Wood, Steve Winwood and Dave Mason, as did Buddy Miles, Al Kooper and others.

Is it a coincidence that the only Hendrix album containing a Dylan cover had the word "Dylan" in the name- Electric Ladyland?
