Alexander Kain came to UW-Madison from Kenosha in 2018 with dreams of becoming the next up-and-coming hip-hop artist. Walking to class one day, he came across a table promoting LÜM (Live Undiscovered Music) — a streaming and social media app — on East Campus Mall. A year later, he has more than 30,000 followers on the app, connections to Travis Scott’s manager and a performance at Freakfest under his belt.
