Today’s featured MP3 song of the day over at Amazon today is a previously unreleased live version of Voodoo Child (Slight Return) by the Jimi Hendrix Experience for only $.99 (down from $1.29).

The song is from a live recording of the Jimi Hendrix Experience from October 1968 at the Winterland Ballroom in San Francisco, CA from the live album Winterland, released yesterday. The entire album is available in MP3 for $29.99 (41 tracks). There’s also two Amazon exclusive versions: a 5 CD Box Set for $40.99; and 8 LP + 1 CD Box Set for $60.79. The songs on Winterland were taken from six shows recorded over three days (October 10, 11 and 12, 1968) at the Winterland Ballroom, which celebrated the two-year anniversary of the Jimi Hendrix Experience and just as the album Electric Ladyland was released.

While everyone knows Hendrix tunes like “Foxy Lady” and “Purple Haze,” in my opinion, “Voodoo Child (Slight Return)” is one of best, and this live version is nearly 8 minutes long — well worth the 99 cents.

Grab this $.99 song deal today while you can, it ends at 11:59PM PST tonight (Wednesday, September 14, 2011). [UPDATE: It’s still on sale, and it looks like it will be for the rest of the week.]
