America's Got Talent Season 10 (AGT 2015) has reached the most exciting stage of the competition with the number of acts being trimmed to just 22 after the quarter-finals. Semi-finals week one will kick off on Tuesday with 11 acts to perform live again in the hope of advancing to the next round.

Only five acts will be selected for the next round and six of them will be shown the doors in Wednesday's results episode. Judges - Howie Mandel, Howard Stern, Mel B and Heidi Klum – can still press the red buzzers in the semi-finals performances to show their disapproval and end an act prematurely but that doesn't necessarily mean the act is eliminated immediately.

Here is the list of 11 acts to perform live on Tuesday:

1) Arielle Baril (Opera singer)

2) Benton Blount (Singer)

3) Drew Lynch (Stand-up comedian)

4) Ira (Singing puppet)

5) Metal Mulisha Fitz Army (Stunt motocross team)

6) Mountain Faith Band (Bluegrass band)

7) Samantha Johnson (Singer)

8) Siro-A (Dance group)

9) The CraigLewis Band (Singers)

10) Derek Hughes (Magician)

11) Oz Pearlman (Mentalist)

Though Metal Mulisha Fitz Army were eliminated in the quarter finals, it was brought back to the show by the judges through wild card.

America's Got Talent Season 10 (AGT 2015) Semi-finals 1 will be telecasted on NBC at 8:00 PM Tuesday (6:30 am IST, Wednesday) and it can be live streamed on NBC official website.
