Diffuser is a rock band from Long Island, NY that formed in 1994 by Tomas Costanza (guitar/vocals), Anthony Cangelosi (guitar), Lawrence Sullivan (bass) and Billy Alemaghides (drums). Originally the band was called Flu 13 and released a 7-inch entitled Edgar's Airwaves and an album entitled Spin Cycle before being signed to The Medicine Label. After being signed they released their second album titled In The Foul Key Of V.
The band signed with major label Hollywood Records in 2001 and changed their name to Diffuser. In 2001 the band released their first album on Hollywood Records titled Injury Loves Melody. Their single "Karma" was included on the Mission: Impossible II Soundtrack, and peaked at number 20 on the Billboard Mainstream Rock Tracks chart.
Lawrence and Billy left the band in 2003 and were replaced by Peter Schojan and Dan Leo on bass and drums respectively. In March the band toured the country with Simple Plan, Gob and Madcap. Their second album, Making the Grade was released in July of that year. The songs "I Wonder" and "Get It On" were used in the 2003 movie Freaky Friday. The song "Get It On" also appeared on the soundtrack for the Outlaw Volleyball video game. The first 150,000 copies of the video game had contained a bonus music sampler from Diffuser.
In the fall of that year the band joined Hoobastank and The All American Rejects on the Nokia Unwired Tour. The band did their final US tour in January 2004 with Spitalfield and Silverstein which followed by a tour in Japan in March. In April Hollywood Records dropped them and they disbanded shortly after. Dan later joined Action Action with ex-members of The Reunion Show and Count The Stars. Diffuser has recently gotten back together and according to their myspace, plan to release a new album in Spring of 2008 and re-release some Flu 13 albums.
