Brian Molko of Placebo will be at the London Roundhouse for the iTunes Festival on July 14

Four more acts have been added to the line-up for this year’s iTunes Festival.

The iTunes Festival, now in its third year, is taking place at the London Roundhouse throughout July.

The four new confirmed acts and dates for the iTunes Festival are:

Placebo (July 14)

Calvin Harris (July 18)

Bloc Party (July 20)

Mika (July 31)

Tickets are free but are only available to competition winners only.

Fans who cannot win tickets will be pleased to hear that tickets are still available for other live shows featuring the same artists as those announced for the iTunes Festival.

Placebo, whose album Battle for the Sun entered this week’s album chart at number eight, will be touring the UK this December.

The Placebo tour kicks off at the Birmingham LG Arena (December 8 ) before stopping off at the London O2 Arena (December 9), Manchester Central (December 12) and the Glasgow SECC & Clyde Auditorium (December 14).

Meanwhile, Calvin Harris recently revealed that he is going to write and record a song in Los Angeles in December with Katy Perry for her next album.

The Calvin Harris tour begins at the LCR of the University of East Anglia (October 15) and will also play at the Leeds O2 Academy (October 21), Manchester Academy (October 24) and Glasgow O2 Academy (November 4) plus many more.

Also with plans for new material are Bloc Party, who plan to release a brand new single called One More Chance in August, which does not appear on their most recent album Intimacy.

The Bloc Party tour, called Bloctober, starts at the Blackpool Empress Ballroom at Winter Gardens (October 2) and will stop off at many UK venues such as the Sheffield O2 Academy (October 10), Bristol O2 Academy (October 20), Brighton Centre and ending at the Bournemouth International Centre (October 31).
