Garth Brooks announced on Thursday that he will go into semi-retirement at the end of next year. But first, the country star, 38, said at a Nashville news conference that he will release an album in the spring and may record a duet album with Trisha Yearwood (with whom, it has been rumored though never confirmed, he is said to be romantically linked). What won't be on Garth's agenda is a tour. "I've done my career with the old saying, 'Burn bright, burn fast,' " he said, before adding this bit of modest self-appraisal: "I wasn't going to be somebody that we could come to really appreciate, like Billy Joel and James Taylor, and know that their stuff was timeless." He said he is making the career move in order to spend more time with his three daughters, the youngest of whom is 4. "My children and I are together every day. I've asked my wife to be mother and father long enough." As for when he and wife Sandy will divorce (as they have announced, after 14 years of marriage), Brooks told reporters, "It's our time frame and nobody else's."
