I bought an album from Mac Lethal at a house party like 15 years ago. Its been awesome watching dude blow up. On his last video he took my suggestion to try using the Wim Hof method of deep breathing to see how long he could rap in one single breath. He did 77 seconds. At the end he says "You try it!" and I did just that. I did like 40 seconds. Had fun tho
