LOS ANGELES (REUTERS) - Country music star Garth Brooks cancelled scheduled media appearances this week, saying it would be in poor taste to promote his comeback album during national protests after a grand jury did not indict a white policeman in the fatal shooting of an unarmed black teenager.

Brooks, 52, cancelled appearances on NBC's late-night The Tonight Show and the morning Today show as well as daytime talk show Live With Kelly And Michael and National Public Radio's All Things Considered, the singer's spokeswoman, Nancy Seltzer, said on Wednesday.

"To spend the day promoting our stuff like nothing was wrong seemed distasteful to me," Brooks said in a Facebook post on Tuesday.

The St Louis suburb of Ferguson, Missouri, has been hit by two nights of unrest after the grand jury's decision not to indict police officer Darren Wilson after shooting 18-year-old Michael Brown in August.

The decision also touched off demonstrations in cities such as New York, Los Angeles and Washington.

Brooks was scheduled to perform live on Kelly And Michael on Tuesday, while other appearances were to be taped and broadcast later, Seltzer said.

The singer was set to appear on the Tonight Show on Thursday, and Today on Friday, two sought-after spots at the beginning of the US holiday shopping season.

Brooks, who has sold more than 130 million albums worldwide, released Man Against Machine on Nov 11, his first studio album in 13 years.
