Daniel Michael Andriano (born June 27, 1977 in Elgin, Illinois) is the bassist and co-vocalist of the punk rock band Alkaline Trio.

Andriano is a graduate of St. Edwards High School in Elgin, Illinois. He enrolled in a psychology class and left after he answered a question asking where the word "lunatic" comes from. He returned to the college once only to "get [his] money," stating that the course was a waste of time because he already knew the material. In 1993 he and several friends from the Elgin area formed the punk-ska fusion band Slapstick, with Andriano playing bass and contributing backing vocals. He would remain a member through the release of two full-length albums (Lookit! and a self-titled compilation) until the group's breakup in 1996. After the breakup he and two other ex-members of Slapstick formed the band Tuesday, which released an EP, Early Summer, in 1997 and a full-length album, Freewheelin, later that year.

Alkaline Trio

In late 1997 Andriano was asked by Matt Skiba to join the Alkaline Trio, replacing original bassist Rob Doran. His first release with the band was the 1998 EP For Your Lungs Only. The band has since released eight studio albums, with their ninth album set to be released on April 2, 2013.

Side and solo projects

Andriano played bass on The Falcon's 2004 EP, God Don't Make No Trash -or- Up Your Ass with Broken Glass, at the request of guitarist and lead vocalist Brendan Kelly, and would return in 2006 to play bass and provide vocals for Unicornography. He also played bass guitar on Ben Weasel's 2007 album These Ones Are Bitter. Andriano also performs as a solo act under the name "Dan Andriano in the Emergency Room". His first solo album, Hurricane Season, was released on August 9, 2011 through Asian Man Records. Later that year, Andriano toured Europe with Chuck Ragan, Dave Hause of The Loved Ones, and Brian Fallon of The Gaslight Anthem as part of the 2011 Revival Tour. The following year, Andriano again performed on the North American leg of The Revival Tour alongside Ragan, Cory Branan, Tom Gabel of Against Me!, and Nathaniel Rateliff.
