Hip hop duo The Outhere Brothers sang Boom Boom Boom. The song was released in 1995, and was a single from their album 1 Polish, 2 Biscuits & a Fish Sandwich.
Boom Boom Boom reached number 65 on the Billboard Top 100, and went straight to number 1 in the United Kingdom, Germany and the Republic of Ireland.
The Outhere Brothers consist of Keith "Malik" Mayberry and Lamar "Hula" Mahone. They have been active since 1987, and have had mixed success. They're generally only well known by most people for their singles Boom Boom Boom and Don't Stop (Wiggle Wiggle).
To date they have released three studio albums and two compilation albums. Here's a video of their most famous song, Boom Boom Boom. No doubt I'll have this song stuck in my head for weeks now! Enjoy!
