At the 2008 Edinburgh Fringe, he appeared in three shows each day - a solo hip hop/comedy show called Abandoman, a double act (with Padraig Hyland) titled Bitesized! Improvised! Televised! (in which they improvise over movie clips) and a nightly show at the Gilded Balloon called Carnival des Phenomenes.
As part of the Irish improvising hip-hop trio Abandoman he won the 2010 Hackney Empire New Act of the Year Competition. Broderick in particular was described by Chortle as "an engaging frontman and an incredibly quick and skilful improviser".[1] Abandoman were also winners of the 2010 Musical Comedy Awards.
Rob returned to Edinburgh Festival Fringe in 2010 with fellow Abandoman James Hancox. The duo performed their show Pic N Mixtape to a sell-out crowd.
In the same year Rob and James played a wide variety of venues and nights from comedy clubs to music gigs as well as festivals including Bestival, Latitude, Hop Farm Festival (in both 2010 and 2011) and Altitude festival in Meribel.
