Today (Aug. 5) is the 50th anniversary of the Beatles' 1966 album, Revolver, which played an important role in the development of alternative music. By a strange coincidence, three stars of indie and alternative music, Pearl Jam's Eddie Vedder, Regina Spektor and Sia released their own takes on Beatles classics today.

That said, none of these songs are actually from Revolver. Two of them stem from the same project, Netflix's animated series Beat Bugs, which dropped on Wednesday (Aug. 3). Each 11-minute episode (there are 26) of Beat Bugs takes a Beatles song and builds a story around it that is designed to get children between two and five years old to, as Netflix's Chief Content Officer Ted Sarandos told Rolling Stone, "[learn] about community and about themselves in a way that you wouldn't immediately associate with a Beatles song."

Vedder, who was one of the first people to sign on to the project, took on "Magical Mystery Tour," which is embedded above. Sia, meanwhile, went with "Blackbird," the episode of which, according to Consequence of Sound, literally deals with a blackbird learning to fly. You can hear a clip of that below. Other musicians involved in the project include the Shins ("The Word", Pink ("Lucy in the Sky With Diamonds") and James Corden ("I'm a Loser"). All 26 songs can be streamed or purchased exclusively at Apple Music.

Spektor's cover of "While My Guitar Gently Weeps" also comes from an animated project, although it's the upcoming stop-motion 3D feature film Kubo and the Two Strings, which stars Charlize Theron, Ralph Fiennes, Rooney Mara and Matthew McConaughey. The soundtrack was released today, and her take features a shamisen -- a Japanese lute -- and strings in addition to her own piano playing. You can listen to it below, and the movie opens nationwide on Aug. 19.
