Lloydelee21, Thomas Ades is a young Brithish composer writing some of the most interesting and adventurous orchestral music today; IMO, one of the leading living composers along side the already mentioned John Adams, Part and others already mentioned by Brownsfan. Try "Asyla" with Simon Rattle conducting the City of Birmingham Symphony on EMI; very imaginative music.
Johnny Mandel was (passed very recently) an American jazz composer/arranger with a very distinctive style. He wrote many songs represented as part of the Great American Songbook. Try Shirley Horne's "Here's To Life", songs/ arrangements by Johnny Mandel. One of my very favorite vocal recordings; an absolutely gorgeous recording.
