Since their first EPs for Warp records, Broadcast have often been compared to Stereolab. From their mix of electronica with lounge music to Trish Keenan's vocals, the similarities are there, but Broadcast have always incorporated more science fiction and psychedelic influences. After releasing The Noise Made By People in 2000, Broadcast return with Haha Sound. This time around the presence of live instruments is much more noticeable and it gives the songs more texture. Songs like "Pendulum" and "Man Is Not A Bird" use acid-rock drumming styles to propel the songs forward.
