Brighton alternative rock band Cave Painting (pictured), managed by industry veteran Keith Bourton (Soul II Soul, Public Image Ltd.), proved one of the biggest pulls of the evening, performing only their second ever gig hours after being signed by Keith Wozencroft to his Mercury/Hideout Records label.
Bourton said, "It was a great night at Breakout. It was especially exciting for the band as they came straight to the gig from signing their recording agreement."
It was a night where female talent particularly shone. Pete Tong's new signing to FFRR Records Paper Crows' frontwoman Emma Panas thrilled with her neo energetic performance.
The Future Cut-produced duo are managed by Dougie Bruce at Simon Fuller's XIX Management who said, "Music Week's Breakout was a real joy to attend. I hadn't been before but there was so much great, diverse music and a real buzz around the venue. Paper Crows really enjoyed their set and the opportunity to showcase to a new audience."
Popjustice-championed Wiltshire synth pop act Queen Of Hearts, fronted by the charismatic Liz Morphew, produced the most theatrical show complete with dancers wearing ram's heads.
Manager Mark Pattison said Breakout was "a fantastic experience". "Great crowd, great atmosphere and it was fantastic to be part of a line up containing so much talent," he added.
"There's not a lot of credible nights out there dedicated to new and emerging music-especially as a pop act, so it was great to have the opportunity to play such a great night. For an act like us that is just breaking through, it was a perfect opportunity."
The night was especially heavy with industry A&Rs, many turning out to watch 18-year-old female singer-songwriter Rae Morris, who performed in the overflowing Acoustic Stable.
There was strong attendance for Jake Morley, Josh Flowers and Daughter. Daughter's manager Matt Brown said, "All the stars seemed to align last night and we came offstage to news we're on 6 Music B list so we had a proper celebration. Breakout was a great night, a brilliant opportunity to meet new industry contacts and catch up with old friends.
Breakout - which is free to Music Week readers - is held on the second Wednesday of the month and a co-promotion with All Night Long.
ANL's Gary Prosser said, "Breakout is going from strength to strength. It was an incredibly strong turnout for our best line-up yet. Getting 967 people in including such a huge industry presence has made us feel genuinely excited that our initial plan of putting bands in front of the right people at the right time is proving a complete success."
