The writer is making a play of words based on the big bang theory. The universe (like a rock and roll song) was created (started) with a four to the floor beat (a big bang).

"Even" in this sentence is 连。。。都, NOT 即使 "kicked off" = began or started (in this sentence) "four to the floor beat" = a musical term. It is the basic drum beat in a lot of rock and pop music. You can hear it in this video: http://www.ehow.com/video_2379957_four-floor-drum-beats.html It is a very strange sentence! I guess the writer is saying that music is really important. It is so important that it was here when the universe began.

"a four to the floor "包含彻底的 或者确定 的 意思吧 ，那“a four to the floor beat”应该就是彻底的击中或者打中的意思吧 。。 那"Even the creation of the universe kicked off with a four to the floor beat" 应该 就是即使那宇宙的的创造彻底轰轰烈烈地地拉开了序幕'.... 恩这是我个人的理解 ，我也不知道对不对 ，仅供参考 哈哈
