Lukin left Mudhoney in June 1999, but rejoined the band in December 2000 for a tour that lasted through January 2001. Since then, Guy Maddison has been Mudhoney's bassist.
In 1996 Pearl Jam wrote and recorded a short and fast punk song entitled "Lukin" naming it after Matt Lukin. Lukin describes the song in an interview for the book Everybody Loves Our Town: An Oral History of Grunge: “Vedder had a stalker chick that would come by his house that was freaking him out. He would start to avoid his house after a while, so he would just come by my place. Vedder’d come over and we’d sit ‘round the kitchen and drink and stuff. He would talk about his stalker problem a little bit, but I would just blow it off. It was just drunken talk, throwing darts, having fun. There’d be other people there, sometimes four or five of us. Just me and Eddie and our wives and mutual friends like [then Mudhoney manager] Bob Whittaker. The Pearl Jam song ‘Lukin’ is about how my kitchen’s a sanctuary for him. Also, I was giving him shit about all their songs being too long. That inspired him to make ‘Lukin’ a one-minute song. I’ve always flipped him shit. Never let him be the rock star that he is.”
Since leaving Mudhoney, Lukin has essentially retired from music. Currently, he works as a carpenter in the Seattle area. According to Eddie Vedder, lead singer of Pearl Jam, Lukin is married to a Dutch woman named Manon, whom he met in Utrecht, Netherlands.
