Jonny L, real name John Lisners, is a British drum and bass producer. He has also released music under the alias of Mr. L and was one half of the UK garage duo True Steppers.
He first came to prominence with the rave single "Hurt You So" in 1992 (that single would later be sampled and looped in the 1998 track "Oh Boy" by The Fabulous Baker Boys). He signed to XL Recordings, the same label as The Prodigy and SL2. He produced more rave singles such as "Ooh I Like It" and "Make Me Work".
In 1995, he changed direction producing drum and bass records, beginning with "I'm Leavin'". With that, he produced two other EPs before his first album Sawtooth in 1997. From this album, the hit single "Piper" proved to be a success even though it was extreme in its sound, although on the album there were other electro-influenced tracks. In 1998, the next album, Magnetic, carried on in a similar vein.
He left XL to form his own record label, Piranha Records in 1999. He continued to produce singles, but these had a darker sound to them. He released a single on the record label Metalheadz in 2002 titled "Synkronize" / "Phreak". "Synkronize" featured vocal sampling speculated to be from Brian Harvey of East 17. Another album, 27 Hours a Day followed with the George W. Bush-sampling single "Let's Roll" in 2003.
