Taken from the bands WIKIPEDIA page:

In 1993, drummer Trevor Reilly, guitarist John Carvalho and bassist Jonathan Teves formed the band Adam's Crack and recorded a Nirvana-inspired demo cassette. In 1994 Reilly and Carvalho started a side band with Nuno Pereira on vocals, and others. The side band played one show before disbanding. Members from the two bands would merge into one, taking the name Koen. The line-up of Koen consisted of Pereira (vocals), Reilly (drums), Teves (bass), Carvalho (rhythm guitar) and friend Mat Demelo (lead guitar and trumpet). Under the name Koen, the band released one cassette titled "The Big Fall...", this time with their sound evolving more into skate punk and ska. In 1997, the band changed its name again, this time to Smackin' Isaiah, and released a cassette titled "Give Girls More Beer...". Mat Demelo left the band shortly after. During this time, Reilly would switch between drumming and guitar duties, with an unknown drummer playing in the band for a brief amount of time. Nicholas Angelini was eventually tapped to play drums on a permanent basis. In 1998, the band released another demo cassette, titled "Gets Eaten Alive".

The band's first CD release was on Tank Records, a record label created by Carvalho and Teves. The CD was a split release with the bands Moronique and Merrick, entitled 6:6:6 after the number of tracks each band contributed. Soon after, the band released its debut album, The Way to a Girl's Heart Is Through Her Boyfriend's Stomach. The band considers this their first "real" release, as all the songs had been written after Angelini joined the band. In retrospect, they consider it their most cheerful record. It was reissued the following year on All About Records, but the band stayed with Tank Records to release its second album, Benefits Of Thinking Out Loud. During the album's recording, the band members had a strained relationship as they argued over its production. Six outtakes from the album's recording sessions were compiled onto an EP entitled The Champagne of Bands... We Know Sexy released by Fork in Hand Records. Following its release, Carvalho left the band. Christopher Levesque quickly replaced him.

Their albums are as follows:
