Len is a Canadian alternative rock duo from Toronto, Ontario. The band consists of siblings Marc Costanzo (vocals, guitar) and Sharon Costanzo (vocals, bass) and a revolving lineup of touring and studio musicians.

Best known for their 1999 hit single “Steal My Sunshine,” Len faded soon after. As Marc stated to Stereogum:

We were looking at this whole bigger picture of what’s gonna happen next, and we knew it’s over in terms of generating more money from the rest of the album. So we just kind of backed out in terms of being public figures. We had 200 shows planned, and after 80 shows, we turned the tour bus around and went home. I went back to my house in BC and just hung out with my friends. We were just like, “We need to go home, I’m sick of this shit.” Our manager and the record label said, “You can’t do this.” And we’re like, “Well, we just did it.”
