Were it not exciting enough to discover that karamu -- from Lionel Richie's lyric We're gonna party, karamu, fiesta in the 1984 hit "All Night Long" -- refers to both a vigorous style of dancing and a special feast held during Kwanzaa, this morning we found a special treat in our inbox, courtesy of the Bay Area hip-hop band 75 Degrees, a group whose Wikipedia definition would probably include the phrase "Sly and the Family Stone of hip-hop." 75's new "Christmas Classic" is a special gift to the Bay, featuring an interpolated sample from the Dragnet theme song and an inspirational rap from emcee Rick Bond (who shouts "Feliz Navidad, tricks!" between verses). In this morning's e-mail, Bond enjoined fans to "download the track, burn it, forward it to friends, drop it on a mixtape, spin it on your radio show, spin it during your club set, add it on your MySpace, post it on the streetlight pole in front of your house if you can," adding that this is the second Christmas/Kwanzaa/Chanukah song ever released by a Bay Area hip-hop artist. Can anyone name the first?
