A 14-act line up of Norwich bands, including The Brownies, fresh from a debut slot at Latitude, will be playing at a Howlback Hum all-day free festival on Sunday (2-11pm).

The event, which boasts talent from the likes of My Visor, **** Dress and Rory McVicar, takes place at King Edward VII on Aylsham Road with a barbecue during the day.

Headliners the Brownies have just released their debut album My Knife Your Back on Norwich's NR1 label with top-notch reviews in the Guardian, Artrocker and the NME, which described them as 'sexed-up fight pop'.

The riot-punk five-piece have just come back from a string of tour-dates across the country, culminating in a spectacular performance at this year's Latitude festival on the BBC Radio 1 Introducing Stage, curated by Radio 1's Huw Stephens.

Meanwhile My Visor will be playing new tracks from their forthcoming second album.

Think the vocal intensity of PJ Harvey with comparisons to The Duke Spirit and Led Zeppelin.

**** Dress saw their debut single Suburban Nietzsche Freak become hit of the summer in Spain and Italy and the song's sledgehammer refrain of 'God is dead/ so I listen to Radiohead' scooped them a Spanish tour in November 2008.

Five-piece indie-kids the Gore Vidals, ever-hyperactive HairTraffic Control, Faster ThanRobots and Viva ZeBool complete the line up in the bar.

Acoustic acts in the garden include Rory McVicar, whose debut album was released on Series 8 records and has appeared at Latitude and Exit festivals.

The singer song-writer has featured as artist of the week on Myspace, recorded three sessions for BBC Radio 1 and supported the likes of Bat for Lashes, Eugene McGuiness, Josh T Pearson, Herman Dune, and Euros Childs.

Other acts performing outside are Milly, The Great Shakes, Alloy Ark, Scraps, Mat Riviere , and Chad Mason Songbook.
