Reclusive rapper Eminem thrilled fans at watch company G-Shock's 30th Anniversary concert in New York on Wednesday night (07Aug13) by treating the select crowd to a rare performance of his hits, including The Way I Am and Lose Yourself. It's the second G-Shock summer party the hip-hop star has played - he hit the stage at the same event last year (12) too after signing on as a brand spokesperson.
