Example Input: Question: Was the record company that signed Rising Sons founded before 1900? Passage:In 1964 he moved to Santa Monica, California, and formed Rising Sons with fellow blues rock musician Ry Cooder and Jessie Lee Kincaid, landing a record deal with Columbia Records soon after. The group was one of the first interracial bands of the period, which likely made them commercially unviable. An album was never released (though a single was) and the band soon broke up, though Legacy Records did release The Rising Sons Featuring Taj Mahal and Ry Cooder in 1992 with material from that period. During this time Mahal was working with others, musicians like Howlin' Wolf, Buddy Guy, Lightnin' Hopkins, and Muddy Waters. Mahal stayed with Columbia after the Rising Sons to begin his solo career, releasing the self-titled Taj Mahal in 1968, The Natch'l Blues in 1969, and Giant Step/De Old Folks at Home with Kiowa session musician Jesse Ed Davis from Oklahoma, who played guitar and piano (also in 1969). During this time he and Cooder worked with the Rolling Stones, with whom he has performed at various times throughout his career. In 1968, he performed in the film The Rolling Stones Rock and Roll Circus. He recorded a total of twelve albums for Columbia from the late 1960s into the 1970s. His work of the 1970s was especially important, in that his releases began incorporating West Indian and Caribbean music, jazz and reggae into the mix. In 1972, he acted in and wrote the film score for the movie Sounder, which starred Cicely Tyson. He reprised his role and returned as composer in the sequel, Part 2, Sounder.
