Dylan Keefe (born April 11, 1970, in Minneapolis, Minnesota) is the bassist and one of the founding members of the multi-platinum selling alternative rock band Marcy Playground.

Before joining Marcy Playground, he attended the Berklee Music College of Boston with the band's ex-drummer Dan Reiser, with whom he played in various jazz projects together.

Aside from providing bass guitar for Marcy Playground, he contributed backing vocals on many of the songs on the band's second album, Shapeshifter.

A quote from Dylan Keefe about a day that forever changed his life:[1] "I can divide my personal history into two distinct parts; pre and post May 31, 1995.

As Minneapolis ex pats living in New York City, we quickly learned that we were from the same town, grew up with similar record collections, and had poor but intellectually stimulating parents that sent us to experimental grade schools.

And although John is far from a father figure to me (he's more like the little brother I need to protect from others so I can beat on him myself later), my dad, like a successful drug deal, delivered something to him from under his sleeve as he passed from my street corner.
