Adam Leonard is an English singer-songwriter working mainly in the folk, psychedelic and electronic music fields. His style is often described as lo-fi and the subject matter of his songs somewhat unconventional. Since his debut album How Music Sounds in 2003, he has released many EPs, albums and mini-albums on various small labels. Live performances, which have so far been limited to the UK (Manchester, London and Northern Ireland) are as intriguing as they are rare. In 2008 he opened for British folk musician Steve Ashley. He regularly collaborates with other musicians, most notably Pat Gubler (P.G. Six), Ashley Cooke (Pulco), Gareth Davies, and Steven Collins of The Owl Service, a band for which Leonard provided vocals for their 2010 album The View From A Hill. At the close of 2010, a limited edition album entitled Nature Recordings was released on vinyl only by the London label The Great Pop Supplement. In 2011, Leonard provided the soundtrack to Claudia Heindel's award-winning independent film, Lucky Seven. In 2012, Nature Recordings was issued on CD by Manchester-based label The Northwestern Series.
In 2013 Leonard formed Invaderband, a four-piece "Artrock/Garagerock/Krautrock" group and began gigging locally around Northern Ireland, including a slot at Other Voices in 2014. Occasional solo gigs still took place, including opening for Nick Harper.
Leonard was the winner of UK City of Culture 2013 Resonate Award for Best Song ("My Love").
In 2014, he embarked on the Octopus Project releasing eight albums over an eight-month period. In 2015, Invaderband released two singles ("The Implausible Man" and "Attack of the Pod People"), the latter making the BBC 6 Music playlist in December 2015. Invaderband's debut album was released in January 2017. In September 2017, the Invaderband album was shortlisted for the Northern Ireland Music Prize
In 2018, Leonard released a solo 7" single "Entkommen", on the Polytechnic Youth label, and also collaborated with Irish/French/New York band, Warriors Of The Dystotheque, on the I Know You'll Never Die EP released by Dublin's Reckless Records. The two main tracks were remixed by Le Galaxie and Richard March of Bentley Rhythm Ace.
In January 2021 a new Invaderband album was announced via invaderband.com. The first single from the album 'I Won't Remember You' was released on March 12
